Seattle Seahawks coach Pete Carroll said running back Marshawn Lynch made the decision not to play in Sunday's wildcard play-off, having initially appeared to feature.
The Seahawks won through to the divisional round of the NFL post-season courtesy of a 10-9 victory over the Minnesota Vikings in the absence of Lynch, who missed the trip despite training on Wednesday, Thursday and Friday.
Lynch had looked set to return from the abdomen injury that has sidelined him for seven weeks.
Carroll provided an update on Lynch post-game, telling reporters the 29-year-old did not feel right.
"We finished practice [on Friday] and I went right to you guys, to talk to the media, just going on what I had seen," Carroll said.
"But when he went back to his locker and sat down, he just didn't feel it. He didn't feel like he could go, and that's it.
"He just didn't feel like he had it. There wasn't enough time to build the confidence that he needed to come in and do something. So that's it. He took off and left."
Asked if Lynch would return against the Carolina Panthers next week, Carroll added: "I don't even know. Just wait and see and take it one day at a time."
Lynch finished the regular season with just 417 yards on 111 carries.
