“First game I strained my MCL, played through that,” McDonald told the Maui News. “First quarter against San Jose State I took a shot to the side. The guy that hit me actually knocked himself out.”

McDonald said after the game he went to the hospital for extra tests.

“…I had some internal bleeding in my side that didn’t drain out properly. It was all in my scrotum. … I couldn’t walk for about a week. … I played hurt most of the season. It was pretty brutal,” he said.
