Raiders QB Derek Carr not practicing, rehabbing injury

It's only May, but Raiders OTA's didn't get off on the best footing with their incumbent starting quarterback not practicing. Derek Carr was relegated to spectator for the first day of Raiders OTA practices after sitting out the team's offseason workouts last week as well.

Carr didn't show any noticeable signs of injury and after participating in a bit of light stretching, didn't participate in warmups or drills. According to head coach Jack Del Rio, Carr was rehabbing, but wouldn't reveal what the nature of the injury was.

"He wasn't able to practice today," Del Rio said of Derek Carr. "He joined a couple of guys that were not able to go right now that when they're not able to go, they don't go. They'll rehab. This is the time of year... I know the quarterback generates more interest than others but he's not the only guy that we held out. Everybody's here, working hard, doing what they can. The guys that need to be held out are being held out. They're getting the necessary rehab and they'll join us when they can. Really we're not going to comment on injuries this time of year. In terms of policy we don't get into who's had what and why and different timetables and all those types of things."

UPDATE: According to Jason La Canfora, Carr's injury is his finger and it's nothing to worry about.

I'm told the medical issue holding Derek Carr back from participating in OTA w/Raiders is very, very minor. Nothing to worry about

The other players to whom Del Rio was referring include defensive tackle Dan Williams and middle linebacker Curtis Lofton. Williams was not out on the practice field and Lofton was present but stayed on the sideline watching his teammates throughout.
