A former walk-on at Alabama this week was promoted to the active roster by the Buffalo Bills from the practice squad.

CB Levi Wallace could make his NFL debut on Sunday when the Bills play the New York Jets. Wallace’s roster spot was created by Buffalo releasing Phillip Gaines. Gaines had a rash of pass interference calls in recent weeks.

Gaines had a dislocated elbow, but returned to the starting lineup the last two weeks opposite former LSU star Tre’Davious White. Pro Football Focus gave Gaines a 63.8 grade this season.

Inspired by his father, Wallace lived a dream at Alabama as he went from walk-on to scout-team member to scholarship player to starter for the 2017 CFP national-championship team, AL.com reported.

Wallace signed with Buffalo as a free agent after the 2018 NFL Draft. He was moved to the practice squad when he was cut when the team trimmed its roster from 90 to 53.

“His story’s remarkable,” Bills coach Sean McDermott said of Wallace at Buffalo’s rookie minicamp. “Really a guy that has earned everything he’s gotten. I believe he was a walk-on the first two years at Alabama. That’s not a place where you would associate with walk-ons having a lot of success, and he obviously did.”
