Del Rio didn't have an update on how Rivera was feeling, but expects him back at the team's practice facility Wednesday. I really dont hear Coach (Rivera) when he's here doing, cornerback Ronald Darby said. But to be honest, it did feel a little weird because whats going on and what he's going through, but we've got to keep pushing.

Washington's coach knows he'll struggle during treatment for squamous cell carcinoma but doesn't want his health to be a focus. He wants his team to be “business as usual” and concentrate on football. Doctors told the 58-year-old coaching could take his mind off the chemotherapy procedures needed to get rid of the treatable form of skin cancer. “You never like being chewed out on the field, but that just shows the passion that coach Rivera has on the field," starting center Chase Roullier said. “It just kind of shows you the importance of having that kind of guy around,” Rivera said.
