Bills head coach Chan Gailey revealed Wednesday that Byrd underwent surgery on a groin injury that plagued him throughout the 2009 season, which puts him out indefinitely. His status for the season opener is very much in doubt, though no exact timetable has yet been set for his return. WGR 550 has the details.
Byrd missed the early portions of 2009 training camp due to the same sports hernia injury; it bothered him throughout his record-setting rookie season, ending it prematurely. He had off-season surgery on what was diagnosed as a torn labrum in his hip, which limited his availability throughout the team's spring practices. However, the injury reportedly continued to bother him into training camp.
George Wilson will start at free safety as long as Byrd is out of the lineup.
