Andrew Luck rocked the NFL on Saturday when he confirmed he was retiring.
The 29-year-old, who has battled injuries since entering the league with the Indianapolis Colts in 2012, said at a press conference that his problems had "taken my joy of this game away".
One of the most hyped quarterbacks to enter the NFL in recent years, former first overall pick Luck certainly lived up to the billing when he was able to get on the field.
Here, we take a look at Luck's career in numbers.
171 - The former Stanford Cardinal tossed 171 touchdowns with the Colts. In NFL history, only Aaron Rodgers and Dan Marino threw more in their first 86 regular-season games.
40 - Of those 171, 40 came in 2014 when Luck led the league in touchdown passes. Only eight men have thrown for more in a single season.
53-33-0 - Indianapolis won 53 of the 86 regular-season games Luck started. The Colts won two AFC South titles in 2013 and 2014 and made the playoffs on four occasions in the Luck era.
4 - Luck was named to the Pro Bowl four times and last season he won the NFL's Comeback Player of the Year award.
20 - There were 20 game-winning drives in Luck's career. Only Drew Brees, Russell Wilson and Matthew Stafford have had more since 2012.
28 - The Colts were 28 points down to the Kansas City Chiefs in the playoffs when Luck engineered what was, at the time, the second-biggest postseason comeback of all time on January 4, 2014.
174 - Luck was sacked on 174 occasions in his career, with 156 of those coming in his first five years as a pro and 41 in his rookie campaign.
4,374 - The record 4,374 yards Luck threw as a rookie remains the leading mark of any first-year quarterback.
11 - Luck played the Tennessee Titans on 11 occasions in his career. The Colts won every single game.
