METAIRIE, La. -- New Orleans Saints fans -- and Michael Thomas' fantasy owners -- can relax. The standout receiver was back on the practice field for the portion open to the media Thursday after being held out of drills Wednesday with a knee injury.

Saints left tackle Terron Armstead (shoulder) also participated Thursday after being held out Wednesday.

(UPDATE: Both Thomas and Armstead were listed as limited in full-team drills on the Saints' official injury report Thursday evening.)

Obviously, both are huge factors for the Saints. Thomas has become as much of a true No. 1 receiver as the Saints have ever had in the Sean Payton/Drew Brees era (and draws that type of No. 1 attention from opposing defenses). And Armstead has played at a Pro Bowl level when healthy in his career, though he has been plagued by injuries over the past three seasons.

Thomas remains a must-start player for fantasy leagues, even though Sunday’s opponents, the Chicago Bears, have been playing great defense. Thomas still leads the Saints with 35 catches and 403 receiving yards despite all the attention he has been receiving from defenses -- though his total of two touchdowns is surprisingly low for such a dangerous red zone target.

As for the rest of the Saints' injury report, receiver Willie Snead (hamstring) practiced fully for the second straight day, but guard Larry Warford (abdomen) remained out and is not expected to play Sunday.
