A San Diego, California man was seriously injured while riding personal water craft with friends Friday afternoon at Lake Havasu. The Mohave County Sheriff’s office said 29-year-old Duncan Davies was riding out in front of friends when he ditched his PWC in the water.

A personal water craft operated by one of his friends struck Davies in the head at about 35 miles per hour. Davies suffered a fractured skull and was flown to a Las Vegas hospital for treatment.
