The Jets opened camp by quietly putting star running back Curtis Martin on the physically unable to perform list (PUP). That means that Martin is unable to participate in team practices but can attend meetings and rehab with the team. Also PUPed was starting wide receiver Justin McCareins. The two can be removed from the list and start practicing with the team at any time. In the meantime according to the rules they are not considered as being on the roster so the team may carry extra players in their places until such time that they are activated.
