19-year-old male hockey player

When I first got hit I didn’t know what was going on. I lost my sight and tried to follow the boards back to the bench. My legs felt weak like it was hard to keep my balance. I got the puck along the boards and tried to stick handle but I had no control over it. I tried passing the puck but I could barely see it and could get nothing on it. It was the same with the shot that I took—I couldn’t see the goalie and couldn’t get anything on the shot. Then I scored and I had to follow my teammates back to the bench.
