Gophers safety Cedric Thompson and wide receiver Derrick Engel are being monitored for concussion symptoms after getting shaken up on hits against Michigan on Saturday, defensive coordinator Tracy Claeys said Sunday.

Both players will be re-evaluated on Monday. The Gophers are off next week before playing at Northwestern on Oct. 19.

But if they had to play Sunday, Claeys said they'd be without four defensive backs: Thompson (concussion symptoms), cornerback Martez Shabazz (separated shoulder), cornerback Derrick Wells (recurring shoulder injury) and Briean Boddy-Calhoun, who was lost to a season-ending knee injury Sept. 7.

Claeys said true freshman Jalen Myric is among those who will get a long look at cornerback before the Northwestern game. Claeys also hinted that a safety could be moving to cornerback, with Brock Vereen one candidate, since he's played corner in the past.
