Brazil star Neymar is expected to be back for the Selecao's two warm-up friendlies for the World Cup next month. National team doctor Rodrigo Lasmar said that the 26-year-old should be fit to face Croatia in Liverpool on June 3 and Austria in Vienna a week later, reported the Globo Esporte website. The Paris St Germain striker was expected to rejoin club training this morning after a foot surgery in March.
Neymar has had surgery on his arm. 
You know he had surgery on his foot, but there's no way to know if he's ever had surgery on his arm. The passage doesn't mention it at all. Maybe last year he did, maybe not, no way to know.
