Coach Pete Carroll said afterward he doesn't have a timetable for Lynch's return, but indicated it's not an issue that will keep him out for an extended period of time.
"We've checked it all out, and there is nothing to be alarmed by," Carroll said. "So we'll just have to wait and see."
Lynch was scheduled to have an MRI on Monday that will determine the extent of the injury.
Lynch spent the first part of the game trying to get loose before appearing on the sideline with 7:40 left in the first quarter. He missed the Seahawks' first two possessions, but then got into the mix, finishing with 14 yards on five carries. Lynch also caught one pass for 9 yards.
Lynch was listed as questionable on the injury report with a calf injury.
"He has a sequence that he goes through to get ready to go," Carroll said. "It's happened before where he just can't get into rhythm and get right and all that. So he had a calf [issue] during the week, and his hamstring kind of bothered him a little bit here today. But he just couldn't get ready. He tried to get out there and did a little bit of running and all but couldn't answer it in the second half."
Lynch has not missed a game with the Seahawks since 2011.
