Rex Ryan on Percy Harvin: 'I don't know where he is right now'

HERTFORDSHIRE, England -- Buffalo Bills wide receiver Percy Harvin has grown increasingly frustrated with hip and knee injuries that are expected to sideline him indefinitely but he is not contemplating retirement, a source told ESPN.

The Buffalo News reported earlier Thursday that Harvin was considering retiring because of a lingering hip injury that has limited his practice time this season and kept him out of Sunday's 34-21 loss to the Cincinnati Bengals.

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 against the Jacksonville Jaguars.

"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."

A source told ESPN on Monday that Harvin wasn't expected to play against the Jaguars because of the injury.

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. However, he was listed as probable on their injury report each week until being designated as questionable last week.
