Chicago Bears safety Quintin Demps suffered a broken arm in the 23-17 victory over the Pittsburgh Steelers and will be out an indefinite period of time.
Demps came out in the fourth quarter of Sunday's win and was replaced by former starter Adrian Amos. A 10-year veteran, Demps was acquired from Houston after the Bears struggled to defend against the pass and made a franchise record-low eight interceptions each of the last two seasons.
Bears coach John Fox did not characterize Demps' injury as a season-ending one. The Bears play at Green Bay on Thursday night.
Demps is the third Bears defensive starter lost to injury in three weeks. Linebacker Jerrell Freeman and Freeman's replacement Nick Kwiatkoski both suffered pectoral injuries.
>>Cowboys Stop Cardinals
Dak Prescott flipped head over heels for a touchdown in the first half and capped his night with a 37-yard TD pass that proved to be the game winner and the Cowboys (2-1) bounced back from a pummeling in Denver and beat the Arizona Cardinals 28-17 on Monday Night Football.
Prescott, 13 of 18 for 183 yards, broke a 14-14 tie with a 37-yard scoring pass to Brice Butler with 11:52 to play.
Arizona, with a spectacular catch by Larry Fitzgerald for 24 yards on a third-and-18 play, moved downfield but the drive stalled. Phil Dawson's 37-yard field goal cut the lead to 21-17 with 6:35 left.
Ezekiel Elliott, who gained 8 yards on nine carries against Denver and drew criticism for not hustling after a couple of late interceptions, was bottled up much of the game, but still gained 80 yards on 22 attempts, 30 on one play. He ran 8 yards for the final Cowboys touchdown.
The Cardinals (1-2), in their home opener, got a big game from Fitzgerald, who caught 13 passes for 149 yards, in the process moving ahead of Marvin Harrison into eighth in career receiving yards. The 13 receptions tied a career high.
Carson Palmer had a big first half, completed 15 of 18 for 145 yards and finished 29 of 48 for 325 yards and two scores. He was sacked six times, a career-high three by DeMarcus Lawrence.
Arizona took the opening kickoff and went 82 yards in eight plays. Palmer was 5-for-5 on the drive, capped by a 25-yard touchdown pass to Jaron Brown.
