The Bears on Tuesday elevated quarterback David Fales from the practice squad to the active roster and waived rookie cornerback Bryce Callahan.

Fales was selected by the Bears in the sixth round of the 2014 draft out of San Jose State. He spent most of his rookie season on the practice squad before being promoted to the 53-man roster last Dec. 13. But he did not appear in a game.

David Fales looks for a receiver during the Bears' preseason finale versus the Browns.

Fales didn't practice until the final day of training camp this summer due to an undisclosed illness. But he started the preseason finale against the Browns, completing 14 of 18 passes for 131 yards with two touchdowns, no interceptions and a 134.0 passer rating.

Fales was inactive for the season opener against the Packers. He was waived last Tuesday and re-signed to the practice squad the next day.

Callahan signed with the Bears in May as an undrafted free agent from Rice. He appeared in the first two games of the season, primarily on special teams.

The Bears also made practice-squad moves Tuesday, signing defensive back Demontre Hurst and receiver Deonte Thompson and terminating the contract of receiver Ify Umodu.

Hurst entered the NFL with the Bears in 2013 as an undrafted free agent from Oklahoma. After spending his entire rookie season on the practice squad, he appeared in 15 games with two starts last year, recording 35 tackles and one interception. Hurst played in the season opener before being waived last Saturday.

Thompson has appeared in 14 games over three seasons with the Ravens (2012-13) and Bills (2014), catching 15 passes for 147 yards and averaging 26.8 yards on 22 kickoff returns.
