Newly acquired G Mackenzy Bernadeau is expected to miss 2-3 months after underoing hip surgery to repair his labrum. Bernadeau, who played the previous four years in Carolina, figured to compete for a starting guard spot along with fellow free agent signee Nate Livings (Bengals). Three months from the surgery would get Bernadeau back on Aug. 12, the day before the preseason opener in Oakland.
