Bills rookie running back C.J. Spiller apologized on Thursday for using a gay slur on his Twitter page. Spiller used the term Wednesday while exchanging tweets with former Clemson teammate and Eagles defensive end Ricky Sapp. "Me and Ricky are best friends and we always joke around on there, but I shouldn't have said what I said. If anybody knew how me and Ricky play around on Twitter, pretty much knows that we were just joking and didn't mean any harm. I apologize for the situation," Spiller said. The original tweet has been deleted.
