ALAMEDA — With Denarius Moore having missed most of training camp and Jacoby Ford out for the last 10 days, quarterback Carson Palmer is concerned about being on the same page with two of his most explosive wide receivers when the regular season opens Sept. 10.

“We need a ton of work together,” Palmer said Monday as the Raiders returned to the team facility for practice. “You can never get enough work with a guy, even if he’s played every rep and you’ve played every rep.

“When they’re back, it’s not easy to get up off the couch, or a walking boot, or off crutches and show up and play.”

Moore and Ford both sat out practice Monday, probably won’t practice Tuesday and are unlikely to face the Seattle Seahawks on Thursday. Final cuts are made the following day, and then the Raiders begin preparation in earnest to start the regular season at home before a Monday night television audience against the San Diego Chargers.

Coach Dennis Allen said at the time of Moore’s right hamstring injury that the plan was to bring him along deliberately to ensure he would be ready for Week 1. Ford, who has a sprained left foot, has no structural damage or swelling, Allen said.

Allen said Ford stopped wearing a walking boot but wasn’t sure when he would return.

“There’s going to be a little bit of a process of getting their legs back and their conditioning back, but also their minds and bodies to the speed of the game to get caught up with everything,” Palmer said.

Veteran return specialist Roscoe Parrish has agreed to terms with the Raiders after being released by the San Diego Chargers, according to Profootballtalk.com In seven seasons with Buffalo, Parrish has 135 punt returns for 1,662 yards (12.0 yards per return) and three touchdowns and 29 kickoff returns for 685 yards (23.6 yards per return) and no scores. When asked Monday if the Raiders’ Week 1 return specialist on either kickoffs or punts was not yet on the roster, coach Dennis Allen said, “That’s a possibility. We’ll go through everybody and we’re going to see who’s out there, and if there’s somebody that we feel like gives us a chance to win, we’re going to try and get him.”
