The Bears on Tuesday promoted safety DeAndre Houston-Carson from the practice squad to the active roster and waived receiver Tanner Gentry.
Houston-Carson was selected by the Bears in the sixth round of last year's draft out of William & Mary. He appeared in eight games as a rookie, recording two special-teams tackles. The 6-1, 203-pounder spent the first two weeks of this season on the practice squad.
Gentry is an undrafted rookie who made his NFL debut for the Bears in last Sunday's loss to the Buccaneers, catching two passes for 27 yards. He was elevated to the 53-man roster last Tuesday after spending the first week of the season on the practice squad.
The Bears on Tuesday also made two practice squad moves, signing veteran nose tackle Mike Purcell and releasing running back Josh Rounds. Purcell spent the last three seasons with the 49ers, appearing in 25 games with eight starts.
