Guard MacKenzy Bernadeau suffered a set back in his return from a hip flexor injury, forcing him to undergo hip surgery on Saturday to repair a torn labrum, multiple sources said.
He will be sidelined up to 12 weeks, including the rest of the off season program, organized team activities and the June minicamp. The Cowboys are hopeful he will be able to return for the start of training camp, tentatively set for the last week of July.
Bernadeau signed a four-year, $11 million free agent contract to join the Cowboys in March after spending the last four years in Carolina. He was expected to compete for a starting spot at guard or center.
According to the Cowboys, he initially suffered the hip flexor injury working out in the offseason program. The Cowboys had given him some time away to rehab and were hopeful he could return for the June minicamp.
But that was before he was forced to undergo surgery on Saturday.
