Mariota’s Knee Injury Sends Rookie Athan Kaliakmanis into Commanders’ London Game
By Drooid · · How we work
Core Event: Injury and Immediate Impact
During the Week 4 matchup in London, Washington quarterback Marcus Mariota was sacked on a third-down play and suffered a right-knee injury. He left the field on his own and was ruled out at halftime. Rookie seventh-round pick Athan Kaliakmanis assumed the quarterback duties for the remainder of the game, which the Commanders lost 30-13 to the Indianapolis Colts.
Background & Context: Commanders’ Quarterback Situation
The Commanders entered the contest already without starter Jayden Daniels, who missed his second straight game after dislocating his left elbow in Week 2. Mariota, the veteran backup, had been thrust into the starting role. His injury now forces the team to rely on third-string quarterback Kaliakmanis, while the roster also copes with injuries to wide receiver Terry McLaurin (hamstring), right guard Sam Cosmi (concussion), and defensive end Charles Omenihu (groin).
Data & Statistics
- Final score: Colts 30, Commanders 13.
- Mariota’s passing: 3-of-4 for 46 yards; a 35-yard keeper set up a 6-0 lead.
- Kaliakmanis’ passing: 15-of-33 for 186 yards, 1 TD, 1 INT; 3 rushes for 16 yards.
- The Commanders attempted six passes of 35 + yards, the most since 2021, completing two for 95 yards, including a 47-yard touchdown to Trey Burks.
- Additional injuries: defensive end Laiatu Latu (sack causing Mariota’s injury), left tackle Brandon Coleman (commentary), and tight end Colson Yankoff (emergency backup).
Official Statements & Responses
Coach Dan Quinn told NFL Network that Mariota “re-injured his MCL,” confirming the medical concern and expressing that the team is “gutted for him.” Despite the setback, Quinn emphasized confidence in the rookie, noting “a lot of confidence” in his ability to manage the offense. He also indicated that a decision on signing another veteran backup will depend on the results of Mariota’s upcoming tests.
Medical expert Dr. David Chao, founder of Sports Injury Central, characterized the injury as an MCL issue, noting Mariota’s prior surgery on the same ligament in 2022.
Quinn expressed optimism about Daniels’ recovery, stating the hope is for Daniels to return after a full week of practice, though his participation remains limited.
