Allen was a key starter at center for a Rams team that won Super Bowl LVI. Initially picked in the fourth round of the 2018 draft out of Michigan State, Allen became a full time starter in 2019. He sat out the 2020 season due to injury, but started 16 games in 2021. Named a Pro Bowl alternate that season, Allen instead went to the Super Bowl and won with the Rams. Injuries would derail his next two seasons in Los Angeles, eventually getting released last year. He spent last offseason with the Browns, but did not play in 2024 after suffering a calf injury and getting released. Allen comes away from his six-year career with a ring and the 29-year-old now heads into retirement.

Allen’s career includes a 2021 Pro Bowl-alternate nod, a Super Bowl LVI victory and various season-ending injuries. He most recently earned a 79.8 PFF pass-blocking grade on just 34 regular season snaps in 2023. If healthy, Allen could contribute in a rotational capacity but his brief injured reserve stint, followed by a quick release after his late-July injury, bodes poorly for his 2024 season.

Allen was injured on the third day of camp and will now miss some time as a result. The veteran center was signed by the Browns earlier this offseason after spending the first five years of his career with the Rams. Allen was limited to just five games last season and has played in just 12 games over the last two years. With Allen now out, the Browns went out and added guard Zack Johnson to the roster.

Allen was a fourth-round pick by the Rams in 2018 but was released in February. He’s played in 50 career games in Los Angeles, but injuries over the years have limited him to 32 starts and he ended last season on the injured list after suffering a calf injury in Week 15. The Browns have Ethan Pocic at center, but the only other center on the roster is 2023 sixth-round pick Luke Wypler, so Allen could compete for a back-up spot in Cleveland.
