Derrius Guice finished his NFL preseason debut with 19 yards rushing on six attempts and with Redskins fans holding their breath.

Nearing the end of the first quarter of the Redskins' 26-17 preseason loss to the Patriots on Thursday night, Guice fell awkwardly on his left knee following an extended run and exited the field with the assistance of the team's medical staff.

Guice himself downplayed the severity of the injury following the game, and the team announced that the former LSU running back would undergo an MRI, and on Friday morning, it was revealed that the initial diagnosis was a sprained left MCL.

Guice is expected to undergo the MRI on Friday afternoon to confirm the injury diagnosis.

The awkward landing was the final sequence in Guice's best play of the day — albeit one that was called by for holding — a physical burst with two cutbacks, penetrating all three levels of the Patriots defense. 

It is likely that Thursday night was the first, last and only time Redskins fans will get a glimpse of Guice in preseason play.
