Thielen (hamstring) isn't practicing Friday, Courtney Cronin of ESPN.com reports.
Coach Mike Zimmer wasn't ready to rule Thielen out for Week 11 after missing Thursday's practice, but another absence to close out the week makes it a virtual certainty the receiver won't be available Sunday against the Broncos. The Vikings will announce an official decision on Thielen's status with the release of their final injury report later Friday.
