Arizona's shaky quarterback situation might be even more uncertain after Tuesday's practice.
In preseason action, Gabbert gave Stanton a push for the backup job early, but couldn't sustain such play before Stanton pulled away in the competition. Now, with Carson Palmer sidelined, who takes the starter's reps is up in the air.
Other injuries we're tracking on Tuesday:
- The Washington Redskins put running back Rob Kelley on injured reserve because of ankle and knee injuries. The 'Skins also made a bevy of other roster moves, including placing linebacker Will Compton (Lisfranc sprain) on IR, waiving defensive lineman Brandon Banks, releasing defensive lineman Tavaris Barnes from their practice squad and signing defensive lineman Caraun Reid and running back Byron Marshall.
- The Cleveland Browns placed linebacker Jamie Collins (MCL) on injured reserve Tuesday, ending his season.
- The Seattle Seahawks made a flurry of roster moves Tuesday, placing cornerback Richard Sherman (Achilles) and running back C.J. Prosise on injured reserve. In corresponding moves, the Seahawks signed veteran corner Byron Maxwell and promoted running back Mike Davis to the 53-man roster, the team announced.
