Dahl left game game against Seattle during the second half and did not return. Fisher said the guard suffered a MCL injury, but the severity was still unknown. Depending on the severity, Dahl could return next week or possibly be out for the season. An MCL sprain would likely cost him at least two games with St. Louis having a bye in Week 11. If he suffered a complete tear, Dahl would need surgery and would miss the rest of the season.
The 32-year-old started all eight games this season and has played well. He has the second-highest run block grade on the team, according to Pro Football Focus. The good news for the Rams is if Dahl does miss time, St. Louis appears to have a capable replacement. Shelley Smith replaced Dahl on Monday and while he's only played limited snaps this season, he has performed well.
