Whaley has not been in contact with Harvin, and the team doesn't plan to reach out to him until it returns from London following Sunday's game against the Jacksonville Jaguars.
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.
Asked Friday about the severity of Harvin's injury, Whaley said, "We'll keep that in-house, but I know there's a lot of other things that are going on that it's just not strictly injury-related."
The Buffalo News reported 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."
