Revis sustained a concussion last week in the Jets' dominating win over the Buffalo Bills when teammate Bart Scott accidentally kicked him in the head while attempting to tackle running back C.J.

Ryan stated on Thursday that he was not going to play Revis if he was not 100 percent, which appears to be the case.
