Former Raiders quarterback Rich Gannon was highly critical of the Raiders in a recent rant on his radio show. Raiders fullback Marcel Reece implored Gannon to watch a practice before he questioned the team’s leadership, work ethic and commitment.

On Friday, Gannon showed up as soon as the media were permitted access to practice and watched the proceedings. Gannon is part of the crew assigned to broadcast the Raiders game against the Chargers on Sunday.

At one point, Reece and the rest of the running backs went through a drill 30 feet or so away from Gannon. No words were exchanged.

The day after Gannon railed against the Raiders, he said via Twitter that he “lost himself” in his rant. He acknowledged that there are people within the organization that want to win.

Reece was a guest on Gannon’s show earlier in the day, before Gannon went off on the team he played for and guided to a Super Bowl appearance in 2002.

After Reece heard about the rant, he said:

“My question to Rich is, when is the last time Rich actually came to watch us practice and watch the work that we put in? And for Rich to be a guy who people love, Raider fans love him, the organization has showed him a ton of love and he’s talking about the organization that gave him a chance and let him do his thing here and now he’s just bashing us.

“I’m in the business of fixing problems and not causing them. I invite Rich to a practice, come see how myself and my guys work every day, day in and day out and the excellence that we do demand of each other. That’s what I ask him.”

— In on-field news, quarterback Derek Carr is moving around well at practice and showing no obvious signs of the left knee and ankle sprains he suffered against the Dolphins in London.

Linebacker Sio Moore and fullback Marcel Reece also don’t appear limited in any way, which bodes well for their playing Sunday against the Chargers.

The same can’t be said for right offensive tackle Khalif Barnes, who isn’t at practice once again. Therefore, it seems almost certain that Menelik Watson will get the nod Sunday.

Beyond that, everyone else appears healthy and ready to go, with the possible exception of cornerback Keith McGill. He wasn’t spotted during the media-access window. We won’t know for sure until coach Tony Sparano speaks with the media later today and the injury report is released.
