GLENDALE, Ariz. — The Oregon Ducks warmed up as usual Thursday evening in what could be an unusual circumstance — the possible swan song of football coach Chip Kelly.

As the Ducks prepared to play Kansas State in the BCS Fiesta Bowl at University of Phoenix Stadium, some NFL teams, including the Buffalo Bills and Cleveland Browns, reportedly were in the area, waiting to conduct their formal interviews with Kelly on Friday for their vacant head coaching positions.

Kelly and his rumored UO successor, offensive coordinator Mark Helfrich joined the other Ducks coaches on the field for warmups, with various celebrities on hand, as well.

The Ducks and Wildcats both were looking for the 12th wins of the season, and to finish with only one loss.
