Jon Gruden is not sure if Marshawn Lynch will return to the Oakland Raiders next season.

"I don’t know. I bumped into him," said Gruden. "Some of these players that live locally do come to the facility to get a workout, see the trainer. I’ve been downstairs and met several guys. I have talked to Marshawn briefly. We’ll see. We’ll keep everybody posted. Right now, he’s our leading ballcarrier. He’s our back, and we’re counting on him. Hopefully we get an opportunity to work together. That’s a man that has a lot of respect in this league as a player and I certainly have respect for him also."

Lynch came out of retirement last season to join the Raiders.
