Thielen (ankle), who is listed as questionable for Monday's game against the Bears, is scheduled to go through a pregame workout before the Vikings decide on his status, Jeremy Fowler of ESPN.com reports.
Official word on whether Thielen is playing or sitting out should arrive no later than 90 minutes before the game's 8:15 p.m. ET kickoff, when Minnesota releases its inactive list. After sitting out the Vikings' Week 14 victory over the Steelers with a low-grade left ankle sprain, Thielen wasn't able to practice in any fashion Thursday through Saturday. While the lack of activity normally would hint at an absence, Fowler suggests that Thielen will have a chance to play Monday if he checks out better than expected during his workout.
