Nebraska senior running back Dedrick Mills announced on Tuesday he will turn to professional football.

Mills was Nebraska’s top running back from the last two seasons, after coming to Lincoln from Georgia Tech and Garden City (Kansas) Community College.

While at Nebraska, Mills ran for 227 times over an 18 game span, covering 1,141 yards to become the 67th Husker to amass at least 1,000 career rushing yards.

Mills missed time with a knee injury during the Penn State game in mid-November, and against Rutgers ran for a career-high 191 yards on 25 carries, making six catches for 45 yards. In his first five games this season, Mills ran for 205 rushing yards on 59 carries.

Nebraska head coach Scott Frost managed to address Mills’ departure by adding former USC running back Markese Stepp, who committed to Nebraska on Tuesday. Stepp’s power run game is similar to that of Mills and will likely make him the lead candidate for the starting job in 2021.
