Culpepper visited the Green Bay Packers on April 23 and 24, 2008. He would later turn down the offer from the Packers, $1 million for a one-year contract, claiming the deal was not good. He said he was in contact with a few other teams. In July 2008, it was reported that the Detroit Lions were interested in signing Culpepper, but they never made an offer to him. He worked out with the Pittsburgh Steelers in August 2008, but the Steelers elected to sign Byron Leftwich instead to replace the injured Charlie Batch. On August 29, 2008, Culpepper then changed his mind and stated that he would consider a backup role in Green Bay if they were still interested in him, but the team did not put forth an offer.
