Stidham completed two of four passes for 28 yards in Sunday's 38-12 preseason win over the Cardinals.
The 28-year-old was under center for the Broncos' first possession and led them to pay dirt with a 10-play drive that was capped by a three-yard TD plunge by rookie running back Audric Estime. Stidham appears set as the top backup to 2024 12th overall pick Bo Nix at quarterback, although Zach Wilson's strong performance Sunday after taking over could cause the Denver coaching staff to at least consider a switch in the No. 2 spot.
