(Indianapolis, IN) — Indianapolis Colts quarterback Andrew Luck is retiring from the NFL. The quarterback was on the sideline for the Colts’ preseason game against the Bears and left the field to boos from his hometown fans. Luck was selected first overall by Indianapolis in 2012. The move comes as a shocker as the Colts are preparing for the regular season. Luck had missed the entire preseason battling a calf injury which developed into an ankle issue.
