Authorities say a former player attacked a western Pennsylvania high school football coach at his home, biting the coach so badly he needed 60 stitches to repair his ear.
Police and Sharon coach Jim Wildman said they can't explain why 38-year-old Joseph Koscinski barged into the coach's home Sunday.
Wildman said he didn't even realize Koscinski was a former player until police told him the man's name later.
Sharon police Chief Mike Menster says Koscinski was still being treated at a hospital Monday for the attack in Sharon, about 60 miles northwest of Pittsburgh. But he's already in custody and will be charged with aggravated assault and other crimes.
The 66-year-old coach was rehired this year after an 11-year retirement.
