Louisville running back Michael Bush announced Tuesday he will enter the NFL draft instead of returning to the Cardinals.
The news was first reported by ESPN.com's Pat Forde, who also reported that Louisville has agreed to terms with Tulsa coach Steve Kragthorpe on a five-year deal to replace Bobby Petrino.
Bush, who announced his decision on Tuesday, broke his right leg in Louisville's season-opener against Kentucky on Sept. 3 and hasn't played since. A senior, Bush applied for a medical redshirt in case he decided to come back, but opted for the NFL instead.
Bush was touted as a Heisman Trophy candidate this season after running for 1,143 yards and an NCAA-leading 23 touchdowns as a junior in 2005. He ran for 128 yards and three touchdowns in little over a half against Kentucky, but broke his right leg after being tackled by Kentucky linebacker Wesley Woodyard early in the third quarter.
Bush told reporters last month that his rehabilitation was going well, though he continues to walk with a slight limp and has yet to begin running.
The Cardinals went 12-1 this season, winning the Big East title and the Orange Bowl. Louisville junior quarterback Brian Brohm has yet to announce whether he will return to the Cardinals next season.
