The Philadelphia Eagles have promoted linebacker Alex Singleton to the active roster, per NFL sources.

The Eagles play the Dallas Cowboys in Week 7 when Singleton will make his NFL debut. Philly cut veteran linebacker Zach Brown on Monday, Singleton takes his open spot.

Brown was a second round, 52nd overall selection by the Tennessee Titans in the 2012 NFL draft. He made the Pro Bowl in 2016 after recording 149 total tackles, 97 solo, four sacks, four passes defended, two forced fumbles and one interception for the Buffalo Bills. The 29-year-old has 664 tackles, 17.5 sacks, 22 knockdowns, seven interceptions and two defensive touchdowns on his NFL resume.

Releasing Brown and the Eagles guaranteeing Singleton’s practice roster salary — $136,000 USD — for the entire 2019 season are indicators of Philadelphia’s belief in the young linebacker. Singleton jumps up in salary for being on the active roster to the rookie minimum $29,117.64 USD per game which equals $495,000 USD for an entire 16-game season.

The 25-year-old made 27 tackles and forced a fumble during four pre-season games, one Singleton started and made 14 tackles. He was waived as part of the team’s final training camp cuts despite a strong showing on special teams and defence. Singleton passed through unclaimed which allowed Philadelphia to add him to the practice roster.

The former Stampeder signed with the Eagles after three seasons in Calgary, recording 311 tackles, six forced fumbles, four sacks, and one interception in 54 regular season CFL games while being a key member of the 2018 Grey Cup championship squad.

Back in 2015, the NFL draft came and went without Singleton hearing his name called, although he signed a contract with the Seattle Seahawks as an undrafted free agent. However, Singleton was released when the team whittled the roster down to the final 53 players.

The New England Patriots signed Singleton that day, but let him go on Sept. 15. Following that, the Minnesota Vikings brought Singleton in for the end of the season and waived him in in the off-season.

During the time between New England and Minnesota, Singleton filed for his Canadian citizenship as his mother was born in Toronto. Calgary selected Singleton in the first round, sixth overall of the 2016 CFL draft. He took over the starting middle linebacker job as a CFL rookie.

Singleton made 123 tackles, four sacks, one interception and forced one fumble in 2017 when he won the most outstanding defensive player award. That was followed by a 123-tackle season in 2018 as Singleton was named a CFL all-star for the second straight year.

After a strong training camp and work ethic while in the practice roster in Philadelphia, Singleton has earned the promotion to the Eagles’ active roster.
