Derek Carr is doing everything asked of the quarterbacks in practice today, which bodes well for Carr being able to play against the San Diego Chargers.

Carr suffered ankle and knee sprains in the Raiders loss to the Miami Dolphins in London. The injuries were serious enough for then-coach Dennis Allen to remove Carr from the game and keep him out for the remainder of a 38-14 loss.

However, Carr said last Wednesday that he intended to be back in time for the Chargers game this Sunday. All indications support Carr’s contention.

Backup quarterbacks Matt Schaub and Matt McGloin also are at practice. Interim head coach Tony Sparano said Monday that he won’t divulge who the No. 2 quarterback is for now. Guess is, Sparano won’t share any of his chewing gum, either. So, don’t ask.

Fullback Marcel Reece is back at practice after he missed Monday’s get together with what Sparano termed a “sprain.” Your guess as to what body part is strained.

Linebacker Sio Moore also is healthy enough to take part in practice today, whereas Monday he was working with a trainer off to the side.

Recently signed linebacker Jamar Chaney arrived in time to join his new teammates. He is wearing No. 51.

Right offensive tackle Khalif Barnes still is sidelined with the injury he suffered against the Dolphins. Menelik Watson worked with the first-team line in Barnes’ absence.

The Raiders began practice much later today than they ever did under fired coach Dennis Allen. The thinking goes, if the Raiders practice more around the time that they play the bulk of their games, the better prepared they will be for the games.

Cornerback DJ Hayden was spotted working hard with a team athletic trainer on a field adjacent to where his teammates practiced. Hayden is eligible to come off the physically unable to perform list and begin practicing as soon as next week.

For those interested, I posted a picture and a Tout video of where the football is buried on the practice fields. Sparano had his players join him in burying a football as a symbol of putting to rest the first four games of the season.

There’s also a video of Chaney in action. Follow me on instagram, Tout and Twitter: @corkonthenfl
