The Panthers activated Thielen (hamstring) from injured reserve Tuesday, Darin Gantt of the team's official site reports.
Carolina is on bye Week 11, but since Thielen's 21-day evaluation window came to a close Tuesday, he wouldn't have been eligible to play again this season had the Panthers not activated him. After having his window opened Oct. 23, Thielen was a limited participant in four of the Panthers' ensuing six practices, but he was listed as a non-participant in all three sessions during Week 10, which could hint at a setback in his recovery from the right hamstring injury he suffered back in Week 3. The bye week will provide Thielen with some added healing time, but his status for the Panthers' next game Nov. 24 versus Kansas City is still very much up in the air. Whenever he does rejoin the lineup, Thielen should step back into a prominent role after Diontae Johnson was traded to Baltimore on Oct. 29.
