Jon Gruden has admitted that he isn't sure if the Oakland Raiders have a backup quarterback on their roster.

"I don't know," Gruden said. "You know, we're going to continue to work, continue to see who's available. I thought there were some good moments tonight and there were some moments tonight that weren't good. It's been too inconsistent but I'm not going to say much more tonight until I see the tape, but we're going to continue to evaluate it."

EJ Manuel and Connor Cook have struggled and there may be better options elsewhere.
