Even before Buddy Nix was named the Buffalo Bills' general manager, league sources say there was a "stealth meeting" with Bill Cowher last week.
It is believed that owner Ralph Wilson Jr. joined team president Russ Brandon to gauge Cowher's potential interest to return to coaching.

The Bills, who also met with Mike Shanahan after Dick Jauron was fired, believe talks with Cowher were very productive, the sources added, but gave no indication whether Cowher will take their head-coaching position if it is offered.
Cowher, currently a CBS Sports studio analyst, could not be reached but network executive Robin Brendle offered a "no comment" on the story.
A Bills spokesman did not respond to voice and text messages regarding the Cowher meeting.
Nix will interview interim coach Perry Fewell on Monday, as well as meet with other Buffalo assistant coaches.
