It's time to look inside five Big Ten teams.
Minnesota -- Wide receiver Eric Decker will miss Saturday's game at Wisconsin (ABC, 3:30 p.m. ET) with a high ankle sprain, and the Gophers are working to find ways to replace the Big Ten's receptions leader. Freshman Brandon Green will play a much more prominent role, and Minnesota also will turn to freshman Brodrick Smith and sophomore Ralph Spry, who comes off a two-game suspension for violating team rules. Green, listed as a starter this week, has 12 receptions in his last three games and could blossom into a top-end wideout with extra playing time.
Northwestern -- Running back has become the Wildcats' primary concern after season-ending injuries to starter Tyrell Sutton (dislocated wrist) and backup Omar Conteh (torn knee ligament). Sophomore Stephen Simmons will make his second career start Saturday at Michigan (ESPN2, noon ET), but he'll get help from freshman Jeravin Matthews, a special teams standout who has been moved from wide receiver to running back. Both Simmons and Matthews are small, quick backs, but they'll need to be effective in the passing game, an area where both Sutton and Conteh excelled.
Iowa -- Daniel Murray converted the biggest field goal in recent team history Saturday against Penn State, but he's once again listed as the backup kicker on this week's depth chart. Head coach Kirk Ferentz has confidence in both Murray and freshman Trent Mossbrucker, though it would be hard to see Iowa go against Murray with the game on the line. Mossbrucker, to his credit, has made 13 of 15 field-goal attempts and all 24 extra-point attempts this season. "We went from a situation not knowing where we were at in the spring to feeling confident right now that both guys plan an important role," Ferentz said.
Purdue -- The Boilermakers could use a quarterback rotation Saturday at Iowa. Fifth-year senior Curtis Painter is improving from a separated throwing shoulder, while redshirt freshman Justin Siller has shown enough promise to remain part of the game plan. Painter returned to practice this week, but head coach Joe Tiller said Siller likely will start against the Hawkeyes. Siller is practicing full-go this week after sustaining a bruised sternum against Michigan State. "What I'd really like in a perfect scenario this week would be for Curtis to get healthy enough to execute the two-minute game," Tiller said. "Justin isn't prepared to do that. It's not that he can't do it in the future, it's just how much are you going to heap on this guy now and what are you going to expect him to do."
Indiana -- Head coach Bill Lynch hasn't pinpointed the reason for his team's rash of injuries, but it isn't the playing field at Memorial Stadium. Indiana had to install new turf late this summer after flooding damaged the old surface. Though several players have sustained knee injuries on the home turf, Lynch sees no different between what Indiana has and other fields around the Big Ten. The health watch on offense looks better this week, but Indiana will need to do more shuffling in the secondary as cornerback Richard Council battles a leg injury. The Hoosiers already have lost three secondary starters to season-ending injuries, and walk-on wide receiver Collin Taylor has been moved to free safety, where he'll back up Brandon Mosley.
