Oakland Raiders rookie wide receiver Brice Butler has admitted that he has a lot of work still to do to put himself in contention for a roster spot.

Butler has impressed Raiders coach Dennis Allen with his pre-season performances, but the player said that he would not yet pay too much attention to any praise that might come his way.

"I don't try to let it get to me," The AP quotes Butler as saying. "It's just one game. I just have to keep working. If I play terrible nobody will remember last week. I just have to keep working.

"I honestly don't think I played that good. Until those couple of plays on that one drive I didn't feel good about my play at all.

I definitely have to work on it. Watching tape there was a lot of stuff I can work on. I definitely just have to build on it."

Brice was a seventh-round pick in the 2013 draft.
