Denver Broncos starting inside linebacker Alex Singleton will miss the remainder of the season with a torn ACL in his knee.

Broncos head coach Sean Payton announced the news, adding that Singleton will undergo surgery within the next two weeks.

Singleton, 30, sustained the injury in last week’s win over the Tampa Bay Buccaneers. He suffered the injury in the first quarter but played through it. He reported soreness in the knee after the game, leading to tests confirming the injury.

Singleton was Denver’s leading tackler through three weeks, with 31, also good for tied for eighth in the league. He also had an interception in Week 1.

Singleton is in the second year of a three-year deal worth $18 million he signed with the Broncos in March 2023.

Singleton signed with Seattle as undrafted free agent in May 2015 but didn’t make his NFL debut until 2019 with Philadelphia. He has 633 career tackles, four sacks and three INTs in 79 career games (50 starts) with the Eagles (2019-21) and Broncos.

Justin Strnad is behind Singleton on the Broncos’ depth chart. The Broncos signed linebacker Kwon Alexander to the practice squad on Wednesday and are expected to also sign LB Zach Cunningham to the practice squad.
