Montee Ball is one of the most decorated college running backs of all-time for his record-breaking career at Wisconsin, but he is no longer a Bronco.
Ball, 24, was waived from the Broncos' 53-man roster, the team announced on Sunday.
Denver's 2013 second-round draft pick was the starting running back to open the 2014 season. Former CAL running back C.J. Anderson will take the role for the 2015 season after breaking out last year for 849 yards and eight touchdowns on 179 carries.
In four years at the University of Wisconsin, Ball totaled 5,140 yards carrying the rock and 77 yards on the ground. He holds the NCAA Division 1-FBS record for most career rushing touchdowns and also the most total touchdowns with 83.
Through two seasons in the NFL, Ball has rushed for 731 yards and five touchdowns while averaging 4.2 yards per carry.
The Raiders play the Broncos in Oakland on Oct. 11 and at Denver on Dec. 13.
