Answer:
Hello, first off sometimes we all say things we don't mean when we are upset. If your friend had no ill intent for the player and feels guilty about what he said then he is a good person. He doesn't need to dwell on this and should just remember how this made him feel when talking in the future. It is important to think how the things you say will affect yourself and others and in the future he can learn from this experience and not make the same mistake again. :)
