Shortly after signing with the San Diego Chargers, Jon Runyan announced he'll retire at the end of the season and run for Congress in New Jersey. The 35-year-old offensive lineman said in a statement late Tuesday that he told Republican officials in Burlington County of his plans to challenge Democratic Rep. John Adler in New Jersey's 3rd District. "I look forward to a successful end to my career on the field," Runyan said, "and a spirited campaign against Congressman Adler in 2010."
