C Brian Allen, LT Joe Noteboom returning to Los Angeles Rams

Center Brian Allen is returning to the Los Angeles Rams on a three-year deal, the team announced Monday.

The deal is worth $24 million, a source told ESPN's Adam Schefter.

Allen, 26, started 16 games for the Super Bowl champion Rams last regular season and all four of their postseason games.

Among centers, he ranked No. 14 in ESPN's run block win rate metric (67.3%) and No. 24 in pass block win rate (91.2%) in 2021.

He didn't play in 2020 because he wasn't ready to return to game action after suffering a knee injury in 2019 that ended his season after nine games.

The Rams selected him in the fourth round of the 2018 draft, and he has played 38 games with 25 starts for the franchise in four seasons.

The Rams also avoided a major hole at left tackle by agreeing to terms with longtime backup Joe Noteboom on a three-year deal before he hit the free-agent market.

His deal is worth up to $47.5 million and includes $25 million in guaranteed money, a source told ESPN's Lindsey Thiry.

Noteboom, who was a fill-in starter last season, is expected to assume a starting role in 2022.

Los Angeles also agreed to a deal with versatile backup offensive lineman Coleman Shelton, who started games at center and left guard last season. Shelton got a two-year deal.

Shelton is a possible replacement if starting right guard Austin Corbett leaves. The Los Angeles-area native has become a dependable player on the interior line since being cut by two teams and then joining the Rams for the 2019 season.
