[Kansas City.com] Chiefs coach Romeo Crennel revealed Monday that quarterback Brady Quinn suffered an injury to his ribs in yesterday’s game at Oakland, leaving his status for Sunday’s home finale against Indianapolis in doubt — and leaving the Chiefs’ quarterback situation familiarly muddled.

Crennel said Quinn’s injury would be reevaluated Tuesday, but whether he gets the call under center won’t necessarily depend exclusively on his health. Asked who would start Sunday if Quinn is healthy, Crennel was noncommittal.

He was similarly vague when presented with the hypothetical of Quinn’s absence, allowing for the possibility that Ricky Stanzi could be in line to make his NFL regular-season debut against the Colts.

The severity of Quinn’s injury is unknown, though he was able to finish Sunday’s game in Oakland, completing 18 of 32 passes for 136 yards, only 4.3 yards per attempt.

He was sacked four times and forced out of the pocket numerous others while the Raiders’ defensive line physically dominated the Chiefs’ offensive line.
