Instead, it has become the biggest source of frustration for fans and coaches alike. Now, the group faces a fresh setback just days before a critical matchup. Center Aaron Brewer missed his second straight practice on Thursday due to a concussion. Sports Illustrated reports that Brewer appears unlikely to face the Indianapolis Colts this Sunday. This news effectively shuts the door on any hope of stability for the Dolphins’ front five.A Line That Never Found Its GrooveThere was genuine excitement when the team drafted Kadyn Proctor and brought back Brewer after his All-Pro season in 2025. Those moves suggested the unit would take a massive leap forward. That progress never happened. The run blocking showed promise for a brief stretch around the bye week, but the pass protection remains a disaster. Malik Willis’s struggles were largely caused by poor pass protection, according to Sports Illustrated. Receivers missed routes, and Willis hesitated, but the line failed to hold its blocks.The rankings from Pro Football Focus tell a harsh story about the current state of the group. Brewer sits at 17th out of 36 qualifying centers. That is not terrible, but it is far below his 2025 standard. Right tackle Austin Jackson ranks 71st out of 71 tackles. Jonah Savaiinaea lands at number 69. The only player with a decent grade is left tackle Patrick Paul at 47th. The rest of the line simply cannot get the job done.The Domino Effect of InjuriesWith Brewer out, third-year player Andrew Meyer is almost certain to start at center. This is a massive blow to an offense that already lacks rhythm. Meyer has not shown he can handle the pressure of a starting role in the NFL. Rookie guard Kadyn Proctor faced a similar issue, missing the Week 8 matchup versus the New England Patriots because a concussion prevented any practice. The team cannot keep losing key players to the same injury bug. It creates a cycle of disruption that the coaching staff cannot fix.The Dolphins have other issues to deal with, including the return of defensive tackle Keith Cooper Jr. and the search for a new quarterback. But the offensive line remains the anchor dragging the team down. Expectations were that improvement would begin during the season’s final weeks. Losing Brewer against Indianapolis kills that hope. With a 1-7 record, the Dolphins currently rank No. 3 for securing the No. 1 overall pick in the 2027 NFL draft. A loss to the Colts on Sunday, Nov. 15, would only add to the misery of a broken offensive line.
