The deal does not preclude the Cowboys from signing Sensabaugh to a long-term deal. The Cowboys and his agent, Kevin Conner, have had talks throughout the off-season. Owner and general manager Jerry Jones said the team wants to sign Sensabaugh and Austin to long-term deals, however, the uncertain future of the collective bargaining agreement has made reaching deals more difficult.
