Update your depth charts, please ...
Redshirt freshman defensive end Anthony LaLota has asked for and received his release and intends to transfer from U-M. LaLota, who redshirted in 2009 and hasn't played this season, was rated the nation's No. 13 defensive end in the 2009 class by ESPN recruiting.
Linebacker Mike Jones likely will have season-ending surgery on his broken leg, and defensive end/linebacker Brandon Herron is day-to-day with an ankle injury.
Wide receiver David Gilreath (concussion) doesn't appear on this week's depth chart, and his status for the Arizona State game (ABC, 3:30 p.m. ET) is to be determined. Coach Bret Bielema said Monday that Gilreath needs to overcome any post-concussion symptoms before being able to return. Gilreath had to be taken off the field in an ambulance Saturday after taking a blow to the head on a punt return.
Wide receiver Nick Toon (turf toe), linebacker Chris Borland (shoulder) and defensive end David Gilbert (concussion) all could return to practice Tuesday.
The status of starting right tackle Josh Oglesby (knee) will be determined later in the week.
Bielema also said wide receiver Kraig Appleton would have to earn an associate's degree from a junior college before having a chance to return to the team. Appleton was indefinitely suspended in February and struggled academically before leaving school.
Freshman running back Matt Perez will miss the season after tearing his ACL in practice last week. Perez was a likely redshirt candidate.
Wide receiver Tandon Doss is expected to practice today after missing the season opener with a groin injury. The All-Big Ten receiver will return Saturday at Western Kentucky. Receiver Dre Muhammad also should return after missing time with an ankle injury.
