Indianapolis, IN (SportsNetwork.com) - The Indianapolis Colts placed center Phil Costa on the reserve/retired list on Monday.
Costa, 26, signed with the Colts back in March after spending his first four NFL seasons with the Dallas Cowboys.
"Phil feels it's in his best interest to retire from the game," Colts general manager Ryan Grigson told the team's official website. "We certainly understand and wish him nothing but the best."
The 6-foot-3, 302-pounder participated in 26 games with 20 starts during his four-year tenure in Dallas. He was the main man under center in 2011, starting in all 16 contests for the franchise and helping allow Tony Romo to throw for more than 4,000 yards and record a career-best 102.5 passer rating.
Indianapolis also announced Monday that restricted free agent cornerback Josh Gordy has signed his qualifying offer.
Gordy appeared in 12 games in 2013 and registered nine tackles, three passes defensed, one interception and four special teams stops.
