The LSU Tigers congratulating former All-American defensive back Tyrann Mathieu on his remarkable career and official retirement from football.

Quarterback Derek Carr also decided to call an end to his playing career after two seasons in New Orleans. Carr, a second-round pick in 2014, struggled to recover from an injury in his throwing shoulder. Instead of going through a grueling recovery process to return to the field, he decided to end his career.

Three-time All-Pro safety Tyrann Mathieu announced in a post on his Instagram page that he is retiring from the NFL. The 33-year-old defensive back was entering his fourth season with the New Orleans Saints but won't step onto the field this year.
