The Vikings’ offensive line has suffered another blow.

Aviante Collins, who injured his right bicep in practice last Thursday, was placed on injured reserve Monday, and coach Mike Zimmer said he is out for the season. A source said he will have surgery later this week.

To take Collins’ spot on the roster, the Vikings signed guard Bryan Witzmann, who started 13 games last season for the Kansas City Chiefs.

Collins was in position to be Minnesota’s top reserve tackle, a role that now goes to rookie Brian O’Neill.

“A.C.’s a good football player and we’re going to miss him,” Zimmer said. “But we’re going to continue to build depth, we’re going to push, and I think O’Neill’s getting better.” Related Articles Gale Sayers, Bears Hall of Fame running back, dies at 77

The Vikings announced last week that Collins’ injury was to his elbow, but a source said it is primarily to his bicep. It happened while he was blocking a defensive lineman.

Last month, the Vikings lost starting left guard Nick Easton for the season with a neck injury. Starting center Pat Elflein is still working his way back from shoulder and ankle issues, and he sat out Sunday’s 24-16 season-opening victory over San Francisco at U.S. Bank Stadium.

The 6-foot-7, 320-pound Witzmann, who played in 27 games the past two seasons with Kansas City, worked out for the Vikings late last week. Undrafted in 2014 out of South Dakota State, he spent time with the Houston Texans, New Orleans Saints and Dallas Cowboys without getting into a regular-season game before joining the Chiefs.

Late in the first half against the 49ers, cornerback Trae Waynes was knocked out of the game with a knee injury. Zimmer said he expects Waynes to practice this week in advance of Sunday’s game at Green Bay.
