Chiefs' Cassel Ruled Out Sunday vs. Tampa Bay
KANSAS CITY (AP) -- Chiefs quarterback Matt Cassel has been ruled out for Sunday's game at Tampa Bay with a concussion, and Brady Quinn will start an NFL game for the first time since the 2009 season.
Coach Romeo Crennel said Thursday that doctors have not cleared Cassel after he was hurt in the fourth quarter of a 9-6 loss to Baltimore last Sunday.
Quinn has been taking repetitions with the first team in practice this week. The former first-round draft pick hasn't started a game since he was with the Cleveland Browns.
Ricky Stanzi, the Chiefs' fifth-round draft pick last year, will serve as the backup.
