Michael Floyd

The unbeaten Arizona Cardinals have won two straight games without Carson Palmer at the wheel, but the team's starting quarterback says a mysterious nerve issue in his throwing shoulder is on the mend.

"It's better. It's much, much better," Palmer said late Tuesday, per The Arizona Republic.

Palmer told reporters that "tons of treatment" has "really helped" to awaken the dormant nerve. The veteran passer, though, acknowledged that he's still unable to throw at full velocity.

"Not yet, but I'll get there shortly," Palmer said.

It sounds as if Palmer will return in Week 5, in a matchup against the Broncos. His return should boost the value of both Michael Floyd and Larry Fitzgerald. Drew Standon held down the fort, but Palmer is the superior passer.
