The Vikings wanted to give the sprained left ankle that has bothered Peterson for the last month some extra rest, so he worked in the pool and received treatment instead of taking the field Friday. But coach Leslie Frazier said the move was merely precautionary.
Tight end John Carlson is out against the Seahawks. He still hasn't been cleared for action after a concussion he had in the game two weeks ago. Frazier said he's hoping for "good news" on Carlson next week.
