Former NFL head coach Jimmy Johnson will be a contestant on the 21st edition of CBS reality show "Survivor", Calvin Watkins of ESPNDallas.com reports.

Watkins adds that Johnson's appearance on the show, which will be filmed in Nicaragua, is not expected to interfere with his duties as a studio analyst during FOX's pre-game show on Sundays this fall.

Johnson, who turned 67 last Friday, coached nine seasons in the NFL with the Dallas Cowboys (1989-93) and Miami Dolphins (1996-99), compiling an 80-64 record in the regular season, and a 9-4 record in the playoffs, including back-to-back wins in Super Bowls XXVII and XXVIII.

Hopefully some of his fellow contestants will form an alliance and mess up Johnson's hair.
