Browns' Karlos Dansby ruled out Sunday vs. Bills

Cleveland Browns linebacker Karlos Dansby has been ruled out for Sunday's game against the Buffalo Bills.

The veteran appeared to be ahead of schedule in his return from a knee injury that's sidelined him since Week 11, but was ruled out after missing practice Friday. 

The Browns are banged up on defense, missing Dansby, safety Tashaun Gipson and possibly linebacker Jabaal Sheard.
