"The Miami Dolphins have added to their thin stable of quarterbacks by trading for Tyler Thigpen of the Kansas City Chiefs, a day after learning that Chad Pennington suffered a season-ending shoulder injury.

The Dolphins have sent a 2010 undisclosed draft pick to Kansas City to land the third-string quarterback, who started most of last season and ran a spread offense for the Chiefs.

To make room on the roster for Thigpen, the Dolphins placed Pennington on injured reserve, meaning he will be unable to return this season.

In last season's 38-31 loss to the Dolphins, Thigpen completed 20-of-41 passes for 320 yards and two touchdowns. But he also threw three interceptions, and gained 57 yards on six carries, which includes and eight-yard touchdown run.

Thigpen instantly becomes the most experienced quarterback on the Dolphins' roster, considering he's thrown 426 passes last season.

His mobility and improvisation make him a tough quarterback to plan for, which could make him an asset running the Wildcat offense.

Chad Henne, who is expected to start in place of Pennington, has thrown just 31 passes in his brief NFL career."
