After missing all of last season, the injury troubles keep on coming for Derrius Guice

According to the NFL Network's Ian Rapoport, the Washington Redskins running back had an MRI Monday morning on his knee and is likely to miss some time. 

Rapoport adds that it is not the knee Guice had surgery on last year to repair an ACL tear, but the other knee. The team is hopeful he does not need surgery but are doing a full evaluation. 

After coming into the year with high expectations, Guice gained just 18 yards on 10 carries Sunday in Week 1 against the Philadelphia Eagles. He also caught three passes for a total of 20 yards but did not find the endzone. 

Washington has Chris Thompson, Wendell Smallwood and Adrian Peterson as running backs on their current roster. 

They will host the Dallas Cowboys in Week 2.
