Injuries piling up for Indiana

Posted by ESPN.com's Adam Rittenberg

After staying relatively healthy for most of the preseason, Indiana has seen its sick bay fill up during the first four games.

The secondary remains the biggest concern for head coach Bill Lynch, who has lost starting cornerback Chris Phillips for the season (torn ACL) and sat both starting safeties -- Austin Thomas and Nick Polk -- last Saturday with injuries. Michigan State quarterback Brian Hoyer took advantage, and there's little doubt Minnesota's Adam Weber will do the same. The Hoosiers really need Thomas back from a lower leg injury.

Florida transfer Jerimy Finch eventually will help the Hoosiers, but he got burned for a 82-yard touchdown by Spartans tight end Charlie Gantt with only 1:29 left in the first half. That's a critical mistake for a safety, one that needs to be corrected before the trip to Minneapolis.

Wide receiver also has been thinned by injuries. Top target Ray Fisher missed some time earlier this season, and both Andrew Means and Tandon Doss went down against Michigan State. The Hoosiers boast an exciting freshman wideout in Damarlo Belcher, but they'll need continued production from running back Marcus Thigpen to account for the losses in the passing game.

Lynch also might consider using starting quarterback Kellen Lewis more at wide receiver. Backup Ben Chappell is certainly capable as a passer.
