"The Chiefs want to see more of Tyler Thigpen before making a long-term decision on the second-year player as the team's backup quarterback.

For now, that's what he is. And the Chiefs' backup quarterback situation isn't likely to change - for the next few weeks, anyway.

"Right now," Herm Edwards said Sunday, "we're going with these guys."

Edwards said the team has not ruled out signing or trading for another quarterback, but there is no rush. He said if the Chiefs need another passer, likely a veteran, good players will be available when rosters are cut in two weeks.

"It's a possibility, but it's not like it's our main objective," Edwards said.

Damon Huard is the Chiefs' third quarterback, but he did not play in Saturday night's 27-17 loss to the Arizona Cardinals. Edwards said Huard, a 12-year veteran, doesn't need as many preseason snaps as Thigpen and starter Brodie Croyle. Edwards has said since training camp started that he wanted to devote more time to observing the Chiefs' young quarterbacks, Croyle and Thigpen, who are 25 and 24, respectively.

Thigpen played the entire second half Saturday, completing 16 of 27 passes with a touchdown. He also threw an interception, which was thrown high and tipped by receiver Bobby Sippio, but then returned for a touchdown. Thigpen also overthrew a handful of passes to open receivers before he found Sergiori Joachim in the end zone with 15 seconds to play.

Edwards admitted Sunday that Thigpen's weakness is his lack of experience. Edwards said that in his mind, Thigpen still is a rookie. The Chiefs picked him up last September when he was cut by the Minnesota Vikings. He played in one game with the Chiefs and suffered a season-ending knee injury in early December."
