Ron Edwards will spend the rest of the 2005 season on the sideline after undergoing surgery on his injured right shoulder. Edwards has not yet been placed on the injured reserve list, but that's likely to happen. A fifth-year veteran, Edwards suffered the injury in the first half Sunday against New Orleans. He missed most of the 2003 season with a serious injury to his left shoulder that required surgery. "The good news is it's not as serious as the previous injury," coach Mike Mularkey said.
