Seattle Seahawks rookie defensive end Cassius Marsh left practice early on Wednesday as he slowly walked into the locker room at the team’s headquarters while flanked by members of the training staff.
Marsh banged his knee in a running drill with a couple teammates and retreated inside the team’s facility. He later returned to the sidelines in street clothes.
However, Marsh is expected to have an MRI on his knee to determine the severity of any injury.
Marsh has drawn praise from the Seahawks coaching staff for his quick hands and explosive off the snap, in addition to his ability to play both inside and outside on the defensive line. Marsh was one of Seattle’s strongest performers in the team’s preseason opener against the Denver Broncos last week, racking up four tackles and the team’s only sack in the game.
Marsh has been expected to contribute as a rotational player this season after being selected in the fourth round of the draft.
