Wright signed to back up Hightower
The deal for Wright, according to a source, is worth $2 million.
His addition doesn't change the status of running back Edgerrin James, who hopes to be released when the team finds a replacement for him. Wright was signed to fill the role of backup running back J.J. Arrington, who left for the Denver Broncos.
Wright, who was recruited heavily by Cardinals head coach Ken Whisenhunt, opted for the opportunity in Arizona. Tim Hightower remains the starter and James remains on the roster -- for now.
