Garner, projected to be the Badgers' No. 3 receiver, will undergo surgery Wednesday, coach Bret Bielema told reporters after Tuesday's practice. He'll miss Wisconsin's season opener Sept. 1 against UNLV but should be back for a Sept. 10 game against Oregon State.
The 6-foot-2, 210-pound Garner, who can play wide receiver or tight end, appeared in 10 games last season, mostly on special teams. He was credited with 10 tackles but did not have any receptions.
Wisconsin, which lacks proven depth at receiver behind top options Nick Toon and Jared Abbrederis, was already down a receiver. Bielema said redshirt freshman wideout Chase Hammond will miss four to six weeks following ankle surgery.
