ANN ARBOR -- Michigan will begin the season with two of its four captains on the sideline with injury.

Coach Brady Hoke announced Monday that senior defensive back Courtney Avery will miss two weeks after receiving arthroscopic knee surgery on Saturday.

Hoke said the procedure was done to clean up some cartilage in Avery's knee, and noted that the senior is in good spirits and will "be back soon."

Avery, who was elected a team captain alongside Taylor Lewan, Cam Gordon and Jake Ryan on Sunday, was competing at both cornerback and free safety this season.

With Avery on the shelf, sophomore Jarrod Wilson will get the nod at free safety. Blake Countess and Raymon Taylor will be the team's starting corners.

Avery has made 81 tackles and three interceptions through his three-year career at Michigan.
