2. Robinson's elbow: Michigan senior quarterback Denard Robinson has two 200-yard rushing games this season, so the Gophers have to force him to throw -- especially because Robinson injured his right (throwing) elbow last weekend. Robinson also leads the Big Ten with nine interceptions.

3. Turnover factor: The Gophers only forced one turnover against Purdue -- Michael Carter's interception that he returned 43 yards for a touchdown -- but had chances for probably a half-dozen. They'll need to take advantage of every opportunity to beat Michigan.


5. Gray time: There's a chance junior A.J. Barker, the Gophers' leading receiver, will be out with a right ankle injury. So senior MarQueis Gray, a former quarterback, will likely need to have his best receiving game since 2010. Barker had 135 yards and two TDs last week.
