Reports: QB Luck tells Colts he's retiring

Quarterback Andrew Luck has told the Indianapolis Colts he is retiring, multiple outlets reported Saturday night. Luck, who turns 30 on Sept. 12, is "mentally worn down" and has already met with Colts owner Jim Irsay, according to ESPN. There will be a press conference Sunday to make the news official.

Luck has been battling an ankle injury for four months that took the team a while to properly diagnose. It was initially called a calf issue before the ankle was determined to be the problem earlier this month. He did not practice in full during training camp, and his availability for the season opener was in doubt. Jacoby Brissett, who started 15 games in 2017 when Luck missed the whole year with a shoulder issue, will be the Colts' starter moving forward.
