"I feel quite exhausted. I feel tired and not just in a physical sense," Luck said confirming his retirement during post-game comments Saturday, WISH reported. "Part of my journey going forward will be figuring out how to feel better."
Luck was booed by fans as he left the field after the Colts 27-17 loss to the Bears at Lucas Oil Stadium. Fans learned of his retirement midway through the game.
"Part of our heart is broken tonight," team owner Jim Irsay told WISH.
Luck planned to tell teammates after the game and make a more formal announcement about retiring Sunday. The Colts locker room was closed to media after the game, WISH reported.
Luck, 29, was drafted No.1 overall in 2012 and played seven seasons for the Colts. He led the team to the playoffs multiple times but his career has been hampered by injuries.
Luck has 23,671 career passing yards and threw 171 touchdowns and 83 interceptions. He has a 53-33 record and appeared in four Pro Bowls.
