MADISON, Wis. -- Wisconsin inside linebacker Chris Orr will miss the remainder of the season with a right ACL injury, the school announced Monday.
Orr suffered the injury on his team's first defensive series during Wisconsin's 16-14 victory against LSU on Saturday at Lambeau Field. He was replaced by backup Ryan Connelly, who finished second on the team with seven tackles.
Badgers coach Paul Chryst said Orr received the news Sunday after undergoing an MRI.
"He crutched in and said, 'Just want to make sure you saw me smiling today,'" Chryst said during his weekly news conference. "He goes, 'I'll be back.' I believed him. These kids do put so much into it. You hate it for them."
Orr played in 10 of 13 games last season as a true freshman, making six starts. He ranked sixth on the Badgers with 46 tackles.
Wisconsin already was thin at inside linebacker because last year's leading tackler, T.J. Edwards, suffered a foot injury this offseason and missed the season opener. Edwards' return is not known at this point, though he appears to be close to playing. Orr, meanwhile, will likely be forced to use his redshirt.
"I don't know when he'll have the surgery, but certainly was disappointed," Chryst said. "His mom and dad, brothers, they raised him right. He's got the right perspective on it."
