Thielen (hamstring) didn't practice Thursday, Courtney Cronin of ESPN.com reports.
Common sense hints at a Week 10 absence, after Thielen aggravated his hamstring in the first quarter of Sunday's 26-23 loss to the Chiefs. Coach Mike Zimmer doesn't view the injury as a long-term problem, but the Vikings reportedly expect their star wide receiver to miss Sunday's game in Dallas. With a Week 12 bye around the corner, the team may also take a cautious approach as it prepares for Week 11 against Denver.
