Cardinals quarterback Carson Palmer said his rehab from a broken left arm is on schedule and he is trying to make a return to the field before the end of the season, Kent Somers of AZCentral.com tweets. 
The veteran signal-caller suffered the injury in Arizona’s 33-0 loss to the Rams in Week 7 and was placed on injured reserve. Should he make a return, Palmer would need to practice two weeks before being activated. Though he is hoping to return this season, Palmer did add he was making no assurances.
With the Cardinals a long shot in the NFC wildcard hunt at 5-6, the team would likely want to rattle off a couple of wins before thinking about sending Palmer back out. A win vs. the Rams in Week 13, however, would close the gap in the NFC West to two games.
Palmer was playing well before the injury, throwing for 1,978 yards and nine touchdowns in nine games and would be a welcome addition to a team looking to get hot down the stretch.
No rush.
