Jeff Saturday announced his plans to retire last month at the Pro Bowl in Honolulu. It becomes official Thursday when the veteran center retires as a member of the Indianapolis Colts. The team has planned a noon news conference. Saturday was an offensive cornerstone of the Colts from 1999-2011 before spending last season with the Green Bay Packers. “The years I spent with the Colts were truly remarkable and I am honored to be able to retire as a member of one of the classiest organizations in the NFL,” Saturday said in a statement released by the team. “I also want to thank Green Bay for the opportunity to compete as a member of the Packers last season. “During my time in Indianapolis, I made tremendous relationships with numerous teammates, coaches and staff within the organization. It was also a pleasure playing for Mr. (Jim) Irsay, who is a wonderful owner. He gave tremendous support for my wife and I in all of our community endeavors.’’ Saturday appeared in 197 regular-season games with the Colts, tied for the fourth-most in club history. He was selected to the Pro Bowl five times with the Colts.
