"I don’t know how that’s going to go," Carroll said. "I don’t know how any of these guys are going to go right now. I don’t know."
Lynch turns 30 in April and missed nine regular-season games due to a number of injuries. He had abdomen surgery on Nov. 25, but returned for Sunday's divisional round matchup against the Carolina Panthers.
"We’ll figure it out," Carroll said. "It depends on how he comes back and how he works at it and all that kind of stuff. He had a difficult year physically. He’s never had to recover from an injury like that. He’s never had to deal with that kind of process. And he made it back, to his credit. He worked hard to get back and made it back to play. It just was a terrible opportunity for him to have a chance to have an impact on the game."
Because of the way Sunday's game went, with the Seahawks falling way behind early, Lynch carried just six times for 20 yards.
He carries a cap hit of $11.5 million in 2016, and the team can get $6.5 million back if it parts ways with Lynch.
Asked if he's gotten any indication from Lynch that the running back would like to come back, Carroll said, "I have not gotten that indication. I don't know. Everything is just normal right now. Just everything remains to be known."
