ESPN.com on Wednesday reported that Bills chief operating officer Russ Brandon traveled to Denver and spent seven hours meeting with Shanahan on Monday night and Tuesday morning. Shanahan was quoted as saying he had "an excellent meeting."
Shanahan, however, added the two sides agreed to stay in touch to see what develops. He's been out of football since being fired as Broncos coach after last season.
The Bills (3-7), who host Miami on Sunday, were not immediately available for comment. Perry Fewell made his debut as interim coach last weekend after Dick Jauron was fired.
