Purdue starting running back Ralph Bolden has suffered a torn ACL that will end his season.
Boilermakers coach Danny Hope confirmed Bolden's injury Sunday night. Bolden sustained the injury in the third quarter of Purdue's win against Indiana on Nov. 26. The junior leads the team in rushing with 674 yards and six touchdowns on 148 carries.
After a promising 2009 season, Bolden missed all of the 2010 campaign with a torn ACL suffered in spring practice. He also dealt with an ACL injury during his senior year of high school.
Purdue wraps up the season against Western Michigan in the Little Caesars Pizza Bowl on Dec. 27 in Detroit.
