"PHOENIX (AP) _ Emmitt Smith reached an agreement to join the Arizona Cardinals on Wednesday.
The Cardinals called an afternoon news conference to announce the deal, NFL spokesman Joe Browne said. Terms of the agreement were not disclosed.
The NFL's leading career rusher was released Feb. 27 by Dallas in a salary-cap move agreed to by the Cowboys and Smith. The Cardinals were the only team the 33-year-old Smith visited.
Arizona lost quarterback Jake Plummer and wide receiver David Boston. They have since signed Jeff Blake to replace Plummer and signed safety Dexter Jackson, the MVP of the Super Bowl for Tampa Bay. "
