Injuries are cropping up around the league, and coaches are shuffling pieces to try to find the right fit. Here's a look at five key issues in the Big Ten.
Minnesota -- Just when the Golden Gophers found a viable running threat, they received news that Duane Bennett tore his ACL against Bowling Green and will miss the rest of the season. Coach Tim Brewster will audition three players -- junior Jay Thomas and freshmen Shady Salamon and DeLeon Eskridge -- at the running back spot in hopes of identifying a featured back. The Gophers need more than one capable runner, but Brewster doesn't want a rotation there. Though Thomas has by far the most experience, Eskridge and Salamon are listed behind Bennett on this week's depth chart.
Michigan State -- The Spartans apparently no longer have cornerbacks or safeties, just general defensive backs. Before the season, coach Mark Dantonio moved starting corner Kendell Davis-Clark to safety after projected starter Roderick Jenrette took a leave of absence. Dantonio now is considering switching another starting cornerback, Ross Weaver, to safety after Davis-Clark sustained a shoulder injury against Cal and missed last week's matchup against Eastern Michigan. Davis-Clark is listed as day-to-day but didn't appear on this week's depth chart for Florida Atlantic.
Ohio State -- Cornerback Donald Washington returns from a two-game suspension Saturday against USC (ABC, 8 p.m. ET), but the two-year starter might not retain his job. Ohio State likely will platoon Washington and sophomore Chimdi Chekwa, who has started the first two games. Coach Jim Tressel also seems intent on keeping Jermale Hines in the mix, possibly at nickel back. Hines should get decent playing time Saturday because the Buckeyes don't know whether linebacker/safety Tyler Moeller will be able to play after suffering an injury.
Michigan -- Redshirt sophomore Perry Dorrestein likely will make his season debut as the Wolverines' starting left tackle Saturday at Notre Dame after Mark Ortmann dislocated his elbow last week. Dorrestein previously had backed up Stephen Schilling at left tackle. Michigan already is without two guards who went down with injuries before the season. Coach Rich Rodriguez expects Bryant Nowicki and true freshman Patrick Omameh to fill in behind Dorrestein on the left flank.
Penn State -- The still-unresolved suspensions of starting defensive linemen Maurice Evans and Abe Koroma and the season-ending injury to Jerome Hayes leave the Nittany Lions in a bit of a bind. Both the end and tackle positions have depth issues, and end might be a greater concern as Penn State doesn't have much behind Josh Gaines and Aaron Maybin. One possibility would be moving true freshman Jack Crawford from tackle to end, though Paterno is leery about Crawford's inexperience. If Crawford switches, it puts more pressure on keeping Jared Odrick, Ollie Ogbu and Tom McEowen healthy.
