The injuries continue to mount for the Rams on their interior offensive line. The defending Super Bowl champions lost another starter up front, with Sean McVay indicating Tuesday that Coleman Shelton will be sidelined due to a high ankle sprain.

Shelton, who won the team’s right guard competition out of training camp, had moved to center after Brian Allen‘s Week 1 injury. Allen has not yet returned, but McVay said Shelton will face a four-to-six week return timetable as a result of the injury he sustained against the 49ers.

The Rams played without their starting center (Allen) and left guard (David Edwards) against the Niners, and other options are out of the picture inside as well. The team’s top 2022 draft choice, guard Logan Bruss, suffered ACL and MCL tears in August; right guard replacement Tremayne Anchrum is also out for the year. The Rams finished with third-string options at center (Jeremiah Kolone) and right guard (Alaric Jackson) by game’s end, Jourdan Rodrigue of The Athletic notes.

A UDFA who has been with the Rams for four seasons, Shelton earned his first crack at a starting job this season. He was the team’s only interior-line constant during the first four games, playing guard and center for the injury-battered front. The Rams will need to make another adjustment before facing the Cowboys in Week 5.

The 49ers dropped Matthew Stafford seven times in Week 4, marking the second game this season in which Stafford has taken seven sacks. The Bills began the year with a seven-sack showing, doing so as the Rams lost Allen to injury. Allen underwent a knee procedure shortly after Week 1, but the Rams did not place him on IR. After missing three games, the veteran snapper should be back soon. Edwards was placed in the team’s concussion protocol over the weekend, leaving his status uncertain for the Dallas matchup. The Rams still have their tackles — Joe Noteboom and Rob Havenstein — available, though Noteboom allowed three of San Francisco’s sacks Monday.
