A total of nine players have donned 34, including Cookie Gilchrist, but no one else since Thurman Thomas.
"If you're at the Pro Football Hall of Fame, you're just at the Pro Football Hall of Fame. I live here. I'm still involved with the community and still involved with the Buffalo Bills".

Thomas spent the first 12 seasons of his 13-year career in Buffalo after the franchise selected him in the second round of the 1988 National Football League draft.

The Buffalo Bills will be retiring their third jersey number in franchise history this season, and frankly it seems long overdue. "I really appreciate that and my family appreciates it".
