Derrius Guice has been hampered by a knee injury once again.
The 22-year-old Washington Redskins running back took a hit to his left knee during the team's 20-15 loss to Green Bay on Sunday, and interim head coach Bill Callahan told reporters Monday that Guice has already been ruled out for next Sunday's game against the Philadelphia Eagles.
Guice underwent an MRI on his knee Monday, and Callahandid not knowthe results nor the extent of the injury when speaking to reporters.
According to Sam Fortier of the Washington Post, the injury could reverberate beyond Week 15:
"Some players and Redskins staffers said they believe this isn’t as serious as his previous injuries as a pro—a torn ACL in his left knee that forced him to miss all of last season and a torn meniscus in his right knee that sidelined him for nine games this year.
