Percy Harvin has grown increasingly frustrated with hip and knee injuries that are expected to sideline him indefinitely but he is not contemplating retirement.

Harvin was reportedly considering retirement, according to a report from the Buffalo News.

Harvin did not travel with the Bills to London this week for what coach Rex Ryan called personal reasons, and will not play in Sunday's game.

"I'm not going to say anything more than what we said yesterday about it," Ryan said Thursday. "I don't know where he is right now."

The Bills have held Harvin out of Wednesday practices since the start of the regular season after he missed the entire preseason because of hip soreness.
