Head coach Rich Rodriguez said quarterback Steven Threet (concussion) is improving and should return to practice today. If Threet practices, he will split first-team snaps with Nick Sheridan. Threet made eight consecutive starts before sitting out last week as Sheridan helped Michigan to a 29-6 win at Minnesota.
Running back Brandon Minor (shoulder, wrist, ribs) also is improving but won't practice today. Rodriguez hopes Minor can practice later this week, though it's unlikely the junior will start Saturday against Northwestern (ESPN2, noon ET).
"Obviously he's very questionable for this weekend," Rodriguez said. "We'll see how he responds [Wednesday] and Thursday. He's definitely not going to practice today. He's a tough guy and I'm sure if he's able to go at all in practice this week, he will."
Quarterbacks Kellen Lewis (ankle) and Ben Chappell (head) both should be fine for Saturday's game at No. 8 Penn State after leaving last week's loss to Wisconsin with injuries, head coach Bill Lynch said.
Linebacker Will Patterson (knee) will miss the Penn State game, while cornerback Richard Council (ankle) is questionable and likely will be replaced in the starting lineup by Donnell Jones. Indiana already has lost three starters in the secondary -- cornerback Chris Phillips and safeties Austin Thomas and Nick Polk -- to season-ending knee injuries.
Starting middle linebacker Jaevery McFadden (concussion) has been cleared and will practice today. Right tackle Eric Vanden Heuvel will undergo an MRI on his lower right leg and could return to practice Wednesday.
Fifth-year senior quarterback Curtis Painter (separated throwing shoulder) is improving and should return to practice today. Painter told head coach Joe Tiller that he threw about 50 passes Monday -- the team is off that day -- and experienced minimal pain.
Tiller said Purdue likely will start redshirt freshman Justin Siller for the third consecutive game but could rotate Siller and Painter from series to series against Iowa.
