Philip Rivers may not be done with professional football quite yet. The 44-year-old former NFL quarterback interviewed with the Buffalo Bills on Friday, January 23, for their open head coaching job - a shocking move that may keep Rivers connected to the NFL. Rivers stepped in as quarterback for the Indianapolis Colts for three of the final four games of the 2025-2026 season after the team's top two signal callers - Daniel Jones and rookie Riley Leonard - both went down with injury.
