The Eagles’ NFC East foe Washington Redskins just took a brutal blow.

Derrius Guice, the Redskins 21-year-old rookie running back, is done for the year.

An MRI confirmed the offensive weapon, whom Redskins fans had pinned much of their hopes on, will miss the 2018 season because of a torn anterior cruciate ligament in his left knee.

Guice suffered the injury in the first quarter of Thursday night’s preseason-opening loss to the New England Patriots in Foxborough, Mass. And his first big gain showcased everything he was poised to bring to the Redskins’ offense — and everything Washington stands to lose in his absence: his burst, quick footwork, and impressive upper-body strength.

Guice took a handoff from quarterback Colt McCoy and rumbled 34 yards, spinning and stiff-arming his way downfield until he was tackled near the left sideline on a play that was negated by a holding penalty.

The running back hyperextended his knee while being brought down to the ground by multiple defenders. But despite the limp, Guice, who was hampered by an injury to the same knee during his final season at LSU, was unaware of the extent of the damage done. And little did he know that his final stat line in their 26-17 loss — six carries for 19 yards — would be the extent of his 2018 production.
