Here are some more personnel nuggets from around the league:
Top running back Adam Robinson will practice later Tuesday and is expected to return to the starting lineup Saturday at Northwestern. Robinson missed last week's game at Indiana with an undisclosed injury.
Coach Kirk Ferentz said Robinson went through his regular training and lifting on Sunday and is "fine to go." Ferentz didn't confirm that Robinson suffered a concussion in the Michigan State game.
More good news for Iowa, as defensive coordinator Norm Parker is back in the office in a limited basis as he continues his recovery from foot amputation surgery. He returned home from a rehabilitation center in Cedar Rapids on Friday and was back in the office Sunday.
Ferentz said there's a chance Parker will travel with the team to Northwestern.
"It's very limited but it's a great first step, certainly," Ferentz said. "And I think like anybody in that situation, he's got a lot of ground to cover right now from endurance and strength, that type of thing. But it's a huge step for him."
Ferentz also said Jeff Tarpinian is back to full speed and could start at outside linebacker this week.
As expected, Ohio State will get linebackers Ross Homan and Dorian Bell back from injuries this week against Penn State. Homan, a senior and a three-year starter, has missed the last two games with a foot injury.
Homan went through 7-on-7 drills Sunday.
"Just like the trainer said, the key will be how does he do two days in a row to see if there's any issues," coach Jim Tressel said, "but based upon after Sunday, I would say no doubt [he plays]."
The Boilers once again enter the week anticipating that true freshman Sean Robinson will start at quarterback for Saturday's game against Michigan.
Redshirt freshman Rob Henry is still dealing with considerable pain from the laceration on his throwing hand, and coach Danny Hope said the redshirt freshman has some tissue damage. Purdue will consider using receiver Justin Siller at quarterback, but only if Siller makes some strides this week from a foot injury. Siller started three games at quarterback in 2008 and led Purdue to a win against Michigan.
"If Justin's able to do more, we'd like to train him as a quarterback," Hope said. "How effective he can be right now, we're not really sure because he still can't run full speed."
Walk-on Skyler Titus is expected to serve as Purdue's No. 2 quarterback against the Wolverines.
Coach Bret Bielema sounded more optimistic Tuesday about starting running John Clay (sprained knee) playing this week against Indiana.
Bielema listed Clay as questionable Monday, but the coach bumped into the running back in the training room Tuesday and said Clay "seemed pretty upbeat" about playing against the Hoosiers. Bielema is hopeful that Wisconsin will have all three of its backs -- Clay, James White and Montee Ball -- available Saturday.
Ball, who has provided a big lift in the last two games and rushed for 115 yards last year against Indiana, is "probably poised to make his first start of the season this week," Bielema said.
The Lions likely will be without defensive end Eric Latimore (wrist) for another week, while defensive lineman Jordan Hill will play against Ohio State after suffering an ankle injury in the second half of the Northwestern win.
Defensive tackle Brandon Kirksey returns from his one-game suspension. Minnesota will be without another defensive lineman, Austin Hahn, who will miss the Illinois game with a torn meniscus that was repaired Monday. Hahn could return for the season finale against Iowa.
