Ok.
Spearing:
A major or match penalty at the discretion of the Referee shall be assessed to a player who spears or attempts to spear an opponent.
NOTE: Spearing shall be defined as stabbing an opponent with the mouth of the stick. Spearing may also be treated as attempt to injure (Rule 30).
NOTE: Attempt to spear shall include all cases where a spearing gesture is made, regardless of whether body contact is made or not.
Again, I have never heard of face masking. Check out
