Notre Dame senior quarterback Everett Golson sprained an AC joint in his right shoulder during Saturday's 43-40 overtime loss to Northwestern

Notre Dame senior quarterback Everett Golson sprained an acromioclavicular (AC) joint in his right shoulder during Saturday's 43-40 overtime loss to Northwestern, Notre Dame head coach Brian Kelly said.

Kelly said he wasn’t sure when Golson was injured but he did not come out of the game. Kelly said Golson’s shoulder felt good enough to throw on Sunday.

Golson went 21-for-40 for 287 yards with three touchdowns, one interception and ran 10 times for 78 yards and another score against the Wildcats.

Kelly did not say if Golson would miss games because of the injury. Golson is completing 61 percent of his passes for 3,044 yards, 27 touchdowns and 12 interceptions. He also has 342 rushing yards and eight touchdowns.

"I haven't gotten a chance to talk to him about it,” Kelly said, according to Yahoo Sports. "There were certainly a couple of throws when he first did it where he put the ball into the ground. You could see that it affected him then. He said he was fine after that, but obviously we missed some throws, especially in overtime. But he said it didn't affect him."

The Irish have lost three of their last four games and dropped out of the Top 25 of the AP Poll.

Notre Dame (7-3) next plays Louisville (7-3) at home on Saturday.
