Kansas City, Mo. ? Quarterback Brodie Croyle will miss the Kansas City Chiefs’ game Sunday against the San Diego Chargers because of a “deep, deep bruise” in his lower back, and veteran Damon Huard will start in his place.

Croyle wasn’t able to practice at all this week, coach Herm Edwards said Friday.

“He threw a little bit, but just can’t move,” he said.

Croyle will not suit up, but could be ready next week, Edwards said. The second-year pro had started the last two games and is designated as Kansas City’s quarterback of the future.

Tyler Thigpen, a rookie claimed off waivers from Minnesota on Sept. 2, will be the backup. Behind him is 12-year veteran wide receiver Eddie Kennison, who hasn’t been under center since high school.

Huard, an 11-year veteran, was 163-of-262 for 1,766 yards in the first nine games, with eight touchdowns and 11 interceptions. He was lifted for Croyle after getting shaken up in a home game against Denver on Nov. 11.

“My body feels a lot better than it did then. That’s one nice thing,” Huard said. “I feel pretty fresh.”

Huard started eight games in place of the injured Trent Green last year and was 5-3. But he did not perform as well when he became the starter this season after Green was traded to Miami.

One of his best games this year was a 30-16 victory at San Diego on Sept. 30, when he passed for 284 yards and two touchdowns, with two interceptions.

Thigpen, drafted in the seventh round last spring by Minnesota out of Coastal Carolina, never has appeared in an NFL game. He took a few practice snaps this week with the first team.
