Los Angeles has added depth on the offensive and defensive lines through the waiver system after all teams reduced their rosters to 53 players.
The Rams were assigned center J.J. Dielman from the Bengals, defensive tackle Quinton Jefferson from the Seahawks, and center Aaron Neary from the Eagles.
The Bengals selected Dielman in the fifth round of this year's draft out of Utah, where he was a three-year starter. After starting at right tackle in 2014 and 2015, Dielman move dinside to play center in his senior season. He was a second-team All-Pac-12 selection as a junior.
Seattle drafted Jefferson in the fifth round last year, and he appeared in three games before suffering a season-ending knee injury. Jefferson earned honorable mention All-Big Ten honors his final season at Maryland with 12.5 tackles for loss and 6.5 sacks in 2015.
Neary signed with the Eagles practice squad at this time a year ago, after spending the offseason program and training camp with the Broncos as an undrafted free agent out of Eastern Washington. He played 46 games in his collegiate career.
Los Angeles will have to make three corresponding roster moves after being assigned three players via the waiver system.
Additionally, the Rams placed linebacker Kevin Davis, linebacker Josh Forrest, wide receiver Nelson Spruce, and running back Lenard Tillery on injured reserve after all four cleared waivers.
