Former pro quarterback Ryan Leaf, still remembered as one of the NFL’s biggest busts, was released on parole from a Montana prison on Wednesday, the Great Fall Tribune reported.

Leaf served about half of his five-year sentence on drug and burglary charges. He also was dismissed from a drug treatment program for threatening a staff member.

Leaf was required to complete a chemical dependency program to be released and granted parole.

He was working on the coaching staff of West Texas A&M when he was arrested.

Leaf, 38, finished third in the 1997 Heisman Trophy voting, and was the No. 2 overall selection in the 1998 NFL draft, one pick behind Peyton Manning and two spots ahead of Charles Woodson.
