ATHENS, Ga. -- Missouri quarterback James Franklin will miss the rest of the regular season after suffering a separated right throwing shoulder Saturday in the fourth quarter of the No. 25 Tigers' 41-26 win against No. 7 Georgia, a source told ESPN's Brett McMurphy.
Franklin suffered a second-degree separation, and the earliest he could return would be for a bowl game, the source said. CBS earlier reported the extent of Franklin's injury.
Coach Gary Pinkel, speaking to reporters Monday, said Franklin would likely be out for three to five weeks without specifying if he was referring to game action or practice.
The senior quarterback, who was plagued by injuries all of last season, watched the remainder of Saturday's game from the sideline with his arm in a sling.
Redshirt freshman Maty Mauk replaced Franklin and made several key plays to help keep the Tigers (6-0, 2-0 SEC) unbeaten.
"I don't want to give you a number that's not accurate, but it looks like the next few weeks (Franklin) will be out," Pinkel said Saturday.
Some of Franklin's teammates talked Saturday as if it could be longer.
"It's a huge loss. I'm saddened by it. I'm a James Franklin fan. It's a huge loss, especially the way that guy had been playing," Missouri senior receiver L'Damian Washington said.
"You can enjoy this win. But at the same time, you really can't because I know most of what I do is because of James Franklin. He's that good. I have faith in Maty Mauk. I know he's going to step up. He has to lead this team right now. He doesn't have a choice."
Franklin was visibly upset in the locker room after the game.
"I feel for him," Pinkel said. "He was having such a great year."
