Colts owner Jim Irsay posted on his Twitter account that he was in Brett Favre's hometown of Hattiesburg, Mississippi on Sunday. However, Favre's agent says he has not heard of any interest from the Colts. Favre, 41, retired in the offseason after a 20-year career and lives in Hattiesburg. "Brad, I'm in Hattiesburg ... is it right or left at the Firechief?" Irsay tweeted Sunday, presumably referring to former Vikings coach Brad Childress, who traveled to Mississippi last July in an apparently successful attempt to keep Favre from retiring. Favre's longtime agent Bus Cook said he hadn't spoken with the former quarterback in a few days, but the "last time I saw him he was on his tractor mowing the back forty."
