Matthieu decided to call it quits after a fantastic 12-year career, which included three Pro Bowls and a Super Bowl ring. He looked set to begin his fourth year with the Saints after not missing a game in his first three, but the 33-year-old decided it was time to move on.

The New Orleans Saints are wasting no time. Just hours after Tyrann Mathieu announced his retirement from the NFL and general manager teasing adding a veteran to the safety position for New Orleans, the Saints are adding some experience in their secondary.

Tyrann Mathieu had himself a great career -- three NFL All-Pro seasons, a trio of Pro Bowls, one Super Bowl ring, 36 interceptions in 12 years with four teams... and one epic nickname ( the Honey Badger! ). But in a heartfelt post on Tuesday before New Orleans Saints training camp, he announced he was calling it quits from the league.
