49ers fear WR Gray sustained collarbone injury in preseason win

SANTA CLARA - The 49ers fear wide receiver Danny Gray might have sustained a significant injury Saturday night. Gray, a second-year pro, had an injury to his collarbone area, 49ers coach Kyle Shanahan said following the 49ers' 21-20 preseason win over the Denver Broncos at Levi's Stadium. The first set of X-rays were inconclusive, so Gray was scheduled to undergo further imaging to reveal the extent of the damage. Gray likely sustained the injury while returning the opening kickoff 23 yards.
