The main topic across the NFL this week has been the start of training camp for many teams, with the Houston Texans kicking off their camp on July 23. Former Texans safety Tyrann Mathieu was one of these players.

Mathieu went on to joke that his five-year-old daughter was upset at him for retiring because she was going to miss getting "dressed up" for his game days. Mathieu and his girlfriend share three kids: 12-year-old and 11-year-old sons, Noah and Tyrann Jr., and a five-year-old daughter, Mila.

New Orleans Saints defensive back Tyrann Mathieu announced Tuesday that he is retiring from the NFL after 12 seasons and three first-team All-Pro selections. The 33-year-old Mathieu, a product of LSU, spent the last three seasons with the Saints and started in all 51 regular season games.
