The mother of a high school athlete who lapsed into a coma as a result of a football game injury has filed claims against a California city school district and fire department, reports television station KGTV. According to the claims, an ambulance standing by at the home game was not used to transport the boy to the hospital after his injury this September. Instead, a second ambulance was called so that an ambulance could continue to stand by at the game in case other injuries occurred. According to KGTV, the boy has regained consciousness and is expected to be in a rehabilitation facility for at least another month. It is not yet known what damages are being sought.
