The Birmingham Stallions have signed running back Bo Scarbrough for the 2024 USFL season, the team announced on Thursday night.

Scarbrough has played in both the Stallions’ seasons, which ended with Birmingham winning the USFL Championship Game in each. But in the 2022 campaign, the former Alabama standout was limited to two rushing attempts in the season-opening game before being sidelined by a knee injury.

Scarbrough had surgery to remove a bone spur from his knee during the season and did not return to the field.

In the first USFL season, Scarbrough didn’t join the Stallions until the fifth game. But in six regular-season contests, Scarbrough ran for 352 yards and one touchdown on 84 carries to finish 10th in the league in rushing despite the late start.

After recording 39 yards on 11 carries and three receptions for 26 yards in the Stallions’ 31-17 victory over the New Orleans Breakers in the semifinals, Scarbrough ran for 135 yards and one touchdown on 13 carries in the 2022 USFL Championship Game. He scored on a 36-yard run and also had a 70-yard run in Birmingham’s 33-30 victory over the Philadelphia Stars.

Scarbrough was a standout at Northridge High School in Tuscaloosa before spending his senior year at IMG Academy in Florida.

In three seasons at Alabama, Scarbrough ran for 1,512 yards and 20 touchdowns on 267 carries and caught 21 passes for 131 yards. The Crimson Tide closed each of Scarbrough’s seasons by playing in the CFP national-championship game.

Scarbrough entered the NFL as a seventh-round draft selection of the Dallas Cowboys in 2018. Dallas released Scarbrough when it reduced its preseason roster to the regular-season limit, but then re-signed him for its practice squad. He stayed with the Cowboys until being released on Oct. 9, 2018.

The Jacksonville Jaguars signed Scarbrough for their practice squad two days later. On Dec. 18, 2018, the Seattle Seahawks signed Scarbrough to their active roster, but he didn’t play in their two regular-season games or playoff contest.

Scarbrough went through the offseason program, training camp and preseason with the Seahawks in 2019, but he didn’t survive the cut to the regular-season roster limit.

Scarbrough joined the Detroit Lions on Nov. 6, 2019, as a member of Detroit’s practice squad.

Scarbrough made his NFL debut in Detroit’s starting lineup 11 days later with former Auburn standout Kerryon Johnson sidelined by a knee injury. He ran for 55 yards on 14 carries and scored a touchdown on his third rushing attempt in a 35-27 loss to the Cowboys. Scarbrough joined Billy Sims, Barry Sanders and Mikel Leshoure as the only Detroit players to run for at least 55 yards and a touchdown in their debuts.

A rib injury that caused Scarbrough to miss a game and Johnson’s return for the final two contests curtailed his opportunities, and he finished with 377 yards and one touchdown on 89 carries for 2019.

Scarbrough started the 2020 season on Detroit’s injured reserve and was released on Oct. 31, 2020, without getting into a game.

Seattle signed Scarbrough to its practice squad 11 days later, and he was elevated to the active roster. But after running for 31 yards on six carries against the Arizona Cardinals on Nov. 19, 2020, he sustained a hamstring injury that sidelined him for the rest of the year.

After being signed as a free agent by the Las Vegas Raiders on Aug. 6, 2021, Scarbrough was released 10 days later.
