Mariota's MCL gives out in London, and now Daniels has to be ready

The Commanders' backup quarterback tore up the same knee he hurt in August, leaving Washington with a rookie as the emergency option and a desperate need for Jayden Daniels to hold up on Sunday against the Giants.

Mariota's MCL gives out in London, and now Daniels has to be ready

The sequence lasted maybe three seconds. Adetomiwa Adebawore drove through the pocket, got to Marcus Mariota on third-and-goal from the 6, and Mariota's right knee bent the wrong way on the turf at Tottenham Hotspur Stadium. He hobbled off. The Commanders, already down to their backup quarterback for the most important stretch of their young season, were now calling on a seventh-round rookie.

That was Sunday morning London time. By Monday afternoon in Ashburn, the diagnosis was official. Coach Dan Quinn confirmed that Mariota suffered a sprained MCL in his right knee against the Colts, the same injury to the same knee he sustained in Week 1 of the preseason. ESPN's Jeremy Fowler reported it was Mariota's second MCL sprain of the 2026 season. The timetable for his return remains uncertain, Quinn said.

So now the math is brutal. Rookie seventh-rounder Athan Kaliakmanis was inserted into the game after Mariota went down, and Washington was unable to keep up with the Colts, losing 30-13 to fall to 1-3. If Daniels is unable to play in Week 5, Kaliakmanis would likely be in line to start against a Giants defense that, while not fearsome, is still an NFL defense.

The good news, and it is real: Quinn reiterated that starting quarterback Jayden Daniels will practice in full this week, with the hope of starting Sunday against the visiting New York Giants. According to The Washington Post's Tashan Reed, Daniels will be a full participant in practice with the aim to play Oct. 11. He has missed Washington's last two games due to the dislocated left elbow he sustained against the Cowboys in Week 2.

The Athletic's Jonathan Jones went further. Sources inside the organization told Jones that if Daniels has a full week of practice, 'that is a positive indication Daniels will be ready to get back behind center.' He was already back on the practice field in London as a limited participant on Wednesday, Thursday and Friday, wearing a brace that keeps him from fully extending the arm.

Still, the word 'full' is doing a lot of work in those sentences. Daniels has played a full game just five times since the start of the 2025 season, adding to Mariota's importance as the bridge quarterback. Now that bridge has a crack in it again. The recurring elbow problem remains a real consideration for Daniels' return. He is expected to play through the same elbow injury he dealt with last year, although offseason surgery has not been ruled out, and Washington is taking a cautious approach before putting him back into action.

A backup plan that keeps breaking down

After leading the Commanders to a 33-31 home win over Seattle in Week 3, Mariota suffered the August injury in a preseason game against the Dolphins, then returned to practice on Sept. 1 after that first setback. He got the team one win. Sunday in London, he went 2-for-2 on field goal drives to give Washington a 6-0 lead before Adebawore ended his day. The final was 30-13.

The Commanders face the 49ers, Eagles and Rams in a daunting three-game stretch after hosting New York, which means a loss to the Giants on Sunday would put them at 1-4 heading into one of the hardest stretches on their calendar. That context is why the Daniels update matters so much right now.

The immediate quarterback picture looks like this: Daniels is the plan, Kaliakmanis is the contingency, and Mariota is done for the foreseeable future. Multiple outlets noted Monday that another MCL injury to Mariota could force Washington to call on a familiar quarterback to fill the void, and that general manager Adam Peters had already drawn criticism for mismanaging the offensive line this offseason, compounding the team's struggles.

One detail that keeps surfacing: Daniels has dislocated the same left elbow twice now, in consecutive seasons. He dislocated his left, non-throwing elbow in Week 2 at Dallas, the same elbow he dislocated last November. The brace he wore in London practices is designed specifically to prevent it from happening a third time. ESPN's John Keim reported the plan is for Daniels to wear a brace 'that keeps his elbow slightly bent to prevent another dislocation.'

For Commanders fans who have watched this franchise cycle through quarterbacking nightmares since 2020, none of this feels unfamiliar. What feels different is that the player they're waiting on is genuinely good. Daniels won Offensive Rookie of the Year in 2024, made the Pro Bowl, and has not thrown an interception yet in 2026. The Commanders are 1-3 without him at full strength. The Giants game, at Northwest Stadium this Sunday, is a winnable game. It may also be a mandatory one.

Wednesday's practice report is the next real data point. If Daniels comes out as a full participant, expect Quinn to confirm the start at his Friday presser. If he's limited again, the calls for Kaliakmanis start getting louder, and a franchise that spent a decade searching for a quarterback will spend another week holding its breath over the one it finally found.
