The Rams released Allen on Wednesday, Stu Jackson of the team's official site reports.
Allen, a 2018 fourth-round pick, has spent his entire NFL career with the Rams and was a key part of the team's efforts in winning Super Bowl LVI. He inked a three-year extension with the team ahead of the 2022 season, but cutting Allen now saves the Rams roughly $4.9 million in cap space.
