Colts placed C/G Phil Costa on the reserve/retired list. The Colts signed Costa to a two-year, $2.7 million contract in March, hoping that he would push Khaled Holmes to replace Samson Satele as Andrew Luck's starting center. Instead, Costa has opted to hang up the cleats for undisclosed reasons. Said GM Ryan Grigson in a statement, "Phil feels it's in his best interest to retire from the game." The Colts are again very needy at center.
