Walsh was withdrawn from training on Thursday but Frazier said that it was just a precautionary measure and that he should be fit to play.

"I think he'll be fine, based on what [head athletic trainer] Eric Sugarman said. He should be fine. Just want to be smart."
Both the Vikings and the Panthers are 1-3 so far this season.
