In the first day of mandatory mini camps, the Raiders lost their number one receiver, Denarius Moore, with a hamstring injury. He was going out for a pass, made a cut and tweaked it. He then limped to the sideline holding his right hamstring and laid face down for a couple of minutes looking as if either the injury was very serious or he was seriously worried it could be.

The trainer came over and worked on it for a few minutes and then Moore got up and gingerly walked off the practice field and into the facility.

Head coach Dennis Allen confirmed it was a hamstring injury after practice:

"Yeah, he's got a little hamstring," said Allen. "He's gonna be fine. You know, we'll evaluate it when we get back here and kinda see where we're at but usually those things might take a couple of weeks or so, so we'll see where he's at."

There is little chance, even if the injury is minor, that we will see Moore back on the practice field for the remainder of mini camps this week. The team is hopeful the injury is not serious and he will be ready by training camp in late July.

Myself or someone else will ask Allen tomorrow what the prognosis is for Moore and I'll have an update at that time.
