Here's the latest check of personnel nuggets from around the Big Ten:
Nebraska senior running back Rex Burkhead is day-to-day for the Michigan game after aggravating his left knee injury for the second time in three weeks Saturday at Northwestern. Coach Bo Pelini is taking a cautious approach with Burkhead and mentioned he's inclined to have the senior rest a week even though the latest aggravation isn't as bad as what happened at Ohio State on Oct. 6. "He felt really good going into the [Northwestern] game, didn't have any issues in practice," Pelini said. "He's frustrated and obviously disappointed he's had to deal with it. It's been too bad." Ameer Abdullah, who leads Nebraska with 514 rush yards and seven touchdowns, will fill in for Burkhead if the senior can't play against the Wolverines. Huskers defensive tackle Chase Rome (concussion) remains out for Michigan, while cornerback Josh Mitchell (ankle) could play and wide receiver Quincy Enunwa (shoulder) will play.
Cornerback Ramon Taylor, who suffered an undisclosed injury last week against Michigan State, is listed as a starter on the depth chart for this week's game at Nebraska. Head coach Brady Hoke said Taylor had "a little boo-boo" and that he would "probably be OK, most likely."
Badgers head coach Bret Bielema said he's unsure if left tackle Ricky Wagner will be available for this week's game against Michigan State. Wagner injured his right knee two weeks ago against Purdue. Ryan Groy filled in at left tackle in the second half against the Boilers and in last week's win over Minnesota.
The Wildcats secondary could be very thin against Iowa this week. Cornerbacks Nick VanHoose and Quinn Evans are doubtful because of injuries, head coach Pat Fitzgerald said. Daniel Jones has been starting ahead of Evans, but VanHoose, who suffered a shoulder injury against Nebraska and was missed down the stretch, is clearly the team's top cover man. In better news, star running back Venric Mark -- who left the second half of the Nebraska game with an undisclosed injury -- is expected to play Saturday, Fitzgerald said.
As expected, Nolan MacMillan is listed as the starter at left tackle in place of the injured Brandon Scherff (leg). Right guard Andrew Donnal (knee) isn't listed on the depth chart for the Northwestern game, as redshirt freshman Austin Blythe is listed as the starter. Mark Weisman and Greg Garmon are listed as co-starters at running back.
Linebacker Joshua Perry and wide receiver Corey "Philly" Brown both are expected to be fine for the Penn State game after getting nicked up against Purdue. The news isn't so good for freshman special teams ace Devan Bogard, who will miss the rest of the season with a torn ACL. "He's one of my favorite guys on the team, top five guy on the team, Devan Bogard," coach Urban Meyer said. "... If we could go out and recruit a hundred Bogards, life would be pretty good around here."
Linebacker Chase Hoobler, who has been battling back issues, is listed on the depth chart for Illinois at backup middle linebacker. Forisse Hardin is listed at starting strong-side linebacker, as Jacarri Alexander had a stinger last week and missed the Navy game.
