The anticipated re-signing of Chad Pennington with the Miami Dolphins has been snagged by the veteran quarterback's desire to have a no-trade clause in his contract, according to team and league sources. Pennington and the Dolphins were expected to reach an agreement on a one-year $2.5 million contract on Thursday afternoon before the stumbling no-trade block, according to another team interested in the quarterback. Pennington, who is recovering well from his third shoulder surgery, has willingly agreed to serve as the Miami's No 3 quarterback, mentoring Chad Henne and Tyler Thigpen, as well as Pat White, but because Pennington has a young family he does not want to move this year, he was holding out for assurances he would not be traded.
