Unsportsmanlike?

[slow whistle]

This happened Fri night BV game. Right at the end of 1st quarter two players go to the ground and one of my partners saw that one sort of pushed and the other pulled him down. Horn goes off and said partner goes to get the two of them basically to warn them to knock it off. One kid stays there to listen the other basically blew him off and turned and walked away...set aside for a moment the question as to why didn't he call the push and/or pull to begin with, what if anything do you do to the kid who blew you off?
