Signed by Baltimore as a non-drafted free agent before joining the Colts in 1999, Saturday ranks among the best undrafted players in the NFL. The Packers center played in two Super Bowls, winning one with the Colts, and was selected for five Pro Bowls. He was twice honored with first-team All-Pro recognition, while his work with the NFL Player's Association to help settle the 2011 lockout made him one of the most respected players in the game. Saturday signed a one-day contract with the Colts on March 7, 2013.
Here are some other prominent players who signed one-day contracts so that they could retire with their old teams.
