The Bills are said to be interested in Miami backup quarterback Tyler Thigpen. He may be available through trade now that the Dolphins have resigned Chad Pennington, who provides depth behind Chad Henne. Miami acquired Thigpen last year after Pennington was lost for the season with an injury. Thigpen played for the Chiefs in 2008 when Chan Gailey was offensive coordinator. He had 2,608 passing yards and 18 touchdowns, in addition to 3 scores on the ground. The 4 year veteran played one game last season against the Steelers, throwing for 83 yards and one touchdown.
