Injury update in coming days

Head coach Dan Quinn said after Friday's 20-7 preseason win over the Dolphins that he'll provide an update on Mariota (knee) on Sunday, John Keim of ESPN.com reports.

Mariota may have picked up a knee injury when he was hit by Tyrel Dodson in the first quarter. Mariota initially stayed in but was favoring his right knee after handing the ball off to Kayton Allen, with the former being tended to by trainers on the ground. Mariota was able to walk off the field on his own, but an extended absence would be a blow considering he appeared in 11 regular-season games (eight starts) last year while Jayden Daniels was sidelined due to injury. Sam Hartman and undrafted rookie Athan Kaliakmanis are the other two quarterbacks on the training camp roster, but if Mariota were to miss time, then the Commanders would likely look to add a veteran QB via free agency or trade.
