What mechanic to use ?

[Kelvin green]

WILDLY swings elbows and clunks guy in chest?

-Whistle-
-Closed fist straight up-
-Immediately two fists crossed at about head height..(or is it closed fist staright up and the youre outta here signal)

Not to contradict my esteemed colleagues but if he were wildly throwing elbows and makes contact you have one of three things

1) you quickly blew your whistle to call the swinging the elbows violation, and he made contact after the whistle... T, two shots and the ball

2) you were slower on your whistle, Intentional foul, two shots and the ball..

3) you were slower on your whistle, Flagrant foul, two shots, the ball, and ejection.

Contact in chest maybe 1 or two, but if he made contact above the chest, neck or head it is flagrant in my book and player is history
