Mackenzy Bernadeau has hip surgery

IRVING, Texas -- The Dallas Cowboys will have to wait before they see guard Mackenzy Bernadeau on the practice field.

According to multiple sources, Bernadeau, who signed a four-year, $11 million deal as a free agent in March, had surgery over the weekend to repair a tear in his right hip and the hope is he could be back in 10-12 weeks.

Bernadeau's agent, Dennis Boyev, declined comment.

Bernadeau has missed most of the offseason conditioning program while doing rehab for his hip. He was signed to be a starter after spending his first four seasons in Carolina. At 6-foot-4, 308 pounds, the Cowboys view Bernadeau as an under-the-radar signing that can help shore up the interior of the line. The Cowboys also signed veteran guard Nate Livings in free agency.

The Cowboys also have second-year guards David Arkin, Bill Nagy and Kevin Kowalski and are intrigued by rookie free agent Ronald Leary. Arkin, a fourth-round pick last year, was not active for a game as a rookie. Nagy, a seventh rounder last year, started three of the first four games at left guard before breaking his ankle.

In 2005, the Cowboys signed guard Marco Rivera to a free-agent deal that included a $9 million signing bonus and he needed back surgery after injuring himself jogging a week later.
