(CNN) It was a sight that gave Liverpool fans plenty of reason for concern as the Reds approach the defining week in the club's season. Leading English Premier League scorer Mo Salah left the field on a stretcher after suffering a head injury in the second half of Liverpool's victory against Newcastle United on Saturday. Manager Jurgen Klopp has said the forward will be assessed before a decision is made on whether he will face Barcelona in the second leg of the Champions League semifinal on Tuesday, where a 3-0 deficit must be overturned if Klopp's men are to reach the final. Salah is placed on a stretcher after suffering a head injury against Newcastle. Salah scores Liverpool's second against Newcastle. "He was OK," Klopp said after the match, further revealing that the player, who scored Liverpool's second goal in a thrilling 3-2 win, watched the rest of the match in the dressing room. "The doctor had to make a decision - on the pitch or off the pitch - and the decision was off the pitch and we accept that of course. "When we came in, he was sitting in the dressing room and had watched the game. He was then fine but of course we have to wait. He got a proper knock in that situation. We'll have to see." In an Instagram post, Liverpool defender Dejan Lovren further eased fans' worries. "Yes he is okay. (He) just can't remember who I am. Don't worry he will be fine, Mo is a monster," was Lovren's reply to a concerned fan. Salah's replacement, Divock Origi, was the matchwinner at Newcastle, scoring the late winner which ensures that the English Premier League title will be decided on the final day of the season. In a blow to Liverpool's Champions League hopes, however, Klopp confirmed that the injured Roberto Firmino would not be fit to face Lionel Messi and co at Anfield on Tuesday.<doc-sep>LIVERPOOL -- Mohamed Salah has been ruled out of Liverpool's Champions League semifinal match against Barcelona on Tuesday after manager Jurgen Klopp confirmed the forward was concussed during Saturday's Premier League win at Newcastle. Liverpool must overturn a 3-0 first-leg deficit when they meet at Anfield in order to reach the Champions League final for the second successive season. But with Roberto Firmino already sidelined with a muscular injury, Klopp revealed on Monday that Salah will also miss the game as a result of the injury sustained when colliding with Newcastle goalkeeper Martin Dubravka at St James' Park over the weekend. "Both of them are unavailable for tomorrow," Klopp said at his prematch news conference at Anfield. "Two of the world's best strikers are not available, and we have to score four goals to go through in 90 minutes. "It doesn't make life easier, but as long as we have 11 players on the pitch, we will try. ... If we can do it, wonderful, and if not, fail in the most beautiful way." Salah is expected to feature against Wolverhampton Wanderers in Liverpool's final Premier League game of the season on Sunday, but Klopp said the clash with Barcelona was too soon for the 26-year-old. "It's a concussion, so Mo is not allowed to play," Klopp added. "He feels OK, but it's not good enough from a medical point of view, that's all. "Together with our supporters this was a long season, and there's a little chance to make it even longer. If not, these are the last two home games of an incredible season. We should celebrate it with a good performance on the pitch and in the stands." Due to medical regulations relating to concussions, Salah will not be able to train until Saturday, but the Egyptian should therefore be able to play against Wolves on Sunday in what could be a title decider for Klopp's team. Salah's absence is a major blow for Klopp and Liverpool, who already face a difficult task in scoring at least three goals to salvage the tie on Tuesday. Without the Premier League's leading goal scorer and Firmino, Klopp could be forced to play both Divock Origi and Daniel Sturridge in attack alongside Sadio Mane. The Liverpool manager fielded Dutch midfielder Georginio Wijnaldum in his forward three during the 3-0 defeat at the Camp Nou on Wednesday, but Klopp is expected to field a more attack-minded player on Tuesday. When asked about the injuries, Barcelona striker Luis Suarez said Liverpool still have plenty of capable replacements to threaten the La Liga champs. "Obviously [Salah and Firmino] are big absences for them," the former Liverpool man said. "But it doesn't change anything in terms of how we approach the game. They have other players to come in with a lot of qualities. "We have a lot of respect for them. Salah is a very important player, in the top three of the world in the last couple of years. It's a big miss for them, but they have players like Origi, [Xherdan] Shaqiri, Sturridge who can come in. Quality players." Defender Trent Alexander-Arnold said Liverpool would have to be fearless to have a chance of progressing. "That's the only way we're going to get a result. If we get caught up in fearing their players, then that's not really going to work," he said. "We have had decent results this season where we have scored more than three goals, and being at home helps us. There's still that sense of belief, but we know it's going to be hard. But anything is possible, especially at Anfield."

The Merseyside giants have the odds stacked against them after losing 3-0 at the Nou Camp in the first leg of their Champions League semi-final tie last week. SEE MORE: Liverpool team news: Key star’s absence from training explained ahead of Barcelona clash Their task of overturning that deficit to advance to the Final has now undoubtedly gotten even more difficult with the club noting that both Salah and Firmino will not feature on Tuesday night. Given Salah has bagged 26 goals and 13 assists in 50 appearances so far this season to keep Liverpool on track to win major honours, Barcelona will surely be buoyed by the fact that the Egyptian international will miss out and won’t pose a major threat to them. However, they showed their class on social media with a tweet in response to Liverpool’s confirmation that Salah will miss out, as seen below. From a neutral perspective, it’s undoubtedly a huge shame that Salah won’t be involved as the two sides are set to put on another spectacle in what promises to be another tense and thrilling European night at Anfield. Nevertheless, Barcelona seemingly appreciate that the showdown loses something with Liverpool seeing their talisman ruled out, and so they have shown great sportsmanship and class to wish him well and bemoan his absence. Time will tell if others can step up and lead the charge for what would be a huge surprise if Liverpool do launch a comeback, as Barcelona are in a very strong position and will be confident that especially with no Salah or Firmino to deal with, they have the defensive strength and attacking threat of their own to finish the job and advance to feature in the Final in Madrid.<doc-sep>Egypt legend Mohamed Aboutrika has revealed that he spoke on the phone with Mohamed Salah after the Liverpool man picked up a head injury against Newcastle. With last night’s game completely in the balance, there were worrying signs for fans of both Liverpool and of the Egypt national team as it appeared that Salah may be ending another season with injury when he went down following his head colliding with Newcastle goalkeeper Martin Dubravka. After the game, another of Egypt’s all time great players Mohamed Aboutrika spoke with Salah on the phone. The 40 year old has since provided some details of what they spoke about. Aboutrika said “I talked to Salah, and he is sound. He has only a mild concussion in his brain. I said to him jokingly, Do you remember me? But he replied that he wanted to forget Dejan Lovren, as he was the source of the pass that caused his injury.” Liverpool are optimistic that Salah can make a recovery for their next game in a do or die Champions League semi final second leg at home against Barcelona where they are looking to overturn a 3-0 deficit from the match at the Nou Camp.<doc-sep>
'Salah cannot play' - Liverpool dealt massive blow for Barcelona semi-final The 26-year-old sustained a concussion during the Reds' Premier League clash at Newcastle on Saturday and will not be risked in the European tie Liverpool boss Jurgen Klopp has confirmed that Mohamed Salah will miss the Champions League semi-final second leg against Barcelona on Tuesday night. The Egyptian was stretchered off the pitch in the second half of a 3-2 victory over Newcastle for the Reds on Saturday, after suffering a concussion . He now joins Roberto Firmino on the sidelines ahead of a crucial showdown with the Spanish champions at Anfield, as Klopp confirmed on Monday. Article continues below The German boss told a press conference: "Salah cannot play tomorrow. He is better in his recovery, but he cannot play tomorrow. "Precaution? No, it's a concussion, which means he is not allowed to play. He feels OK, but it is not good enough from a medical point of view." Barcelona, buffered by a three-goal lead after the first leg, tweeted: "Games like these are for world-class players. Get well soon!" The 26-year-old scored his 22nd Premier League goal of the season against the Magpies, helping Liverpool secure an eighth consecutive domestic victory. He is now on course to win the Golden Boot for the second successive year, and Klopp revealed he will return in time to face Wolves on the final day. However, Liverpool will now have to cope without two of their main attackers against Barcelona, with Xherdan Shaqiri likely to be drafted in following his impressive cameo at St James' Park. Georgino Wijnaldum played up front in Firmino's absence at Camp Nou last week and he could be asked to fill the same role again, but Daniel Sturridge is also an option for Klopp. The Reds are facing a daunting 3-0 deficit after the first leg , with a Luis Suarez goal and a Lionel Messi double earning the home side a comprehensive win in Spain. Klopp acknowledges the size of the task facing his side but is hopeful the Anfield crowd can make a huge difference on the night. "I'd imagine this place will be rocking," he added. "We not only have to score, but we also have to deny Barcelona from scoring. "We know how big the challenge is. We will try 100 per cent. "Two of the world's best strikers are not available and we have to score four goals against Barcelona. "That doesn't make life easy, but we will try. If we can't do it, let's fail in the most beautiful way."
