Herschel Walker, the former Herculean running back of USFL and NFL fame, has launched a new professional sports career – in mixed martial arts. 

Walker, who still holds numerous NFL records some 12 years after his retirement, has signed a multi-fight contract with promoter Strikeforce, SI.com reports. The 47-year-old ex-baller kicks off a 12-week training camp next month in San Jose, Calif. A 1982 Heisman Trophy winner, Walker already holds a fifth-degree Black belt in Tae Kwon Do. 

Walker gained 8,225 rushing yards, 4,859 receiving yards, and 5,084 kickoff-return yards during his dozen years in the NFL. This gave him 18,168 total combined net yards, ranking him second among the NFL's all-time leaders in total yardage at the time of his retirement, according Wikipedia, the online encyclopedia. Walker also scored 84 touchdowns – 61 rushing, 21 receiving and two kick off returns for touchdowns – and is the only player to have more than 10,000 yards from scrimmage and more than 5,000 return yards, all of which were on kickoffs. He is currently ranked eighth all time in all-purpose yards with 18,168, despite spending his first three seasons in the now-defunct USFL.
