John Riggins to Appear on One Tree Hill

With Robert Buckley - who TV Fanatic interviewed last month! - on board One Tree Hill as a sports agent, the potential for athletes to cross over to the small screen is never-ending.

Jerry Rice has already appeared on season seven of the show.

Now, we can report that former NFL running back and Hall of Famer John Riggins will debut on the season's 10th episode. He'll portray Clay's boss, Ken Arthur, a character that may stick around.

Riggins rushed for 11,352 yards in his career. He's previously guest-starred on Law & Order: Criminal Intent and Guiding Light.
