A5 has amassed 5 personal fouls... When the table notifies us, he hears the bad news at the same time and makes very unsportmanlike gesture... For which he is also awarded a T.
Since we have not had time to notify the coach, is this player, with 5 fouls (And One T), already DQ's and considered bench personnel with an indirect to the coach... or is this player still considered a legal player and the T just goes toward the Team total?

NFHS Ruling
 

The player is not DQ'd or bench personnel until you notify the coach. So the T is not chargd indirectly to the Head Coach.
It is charged directly to the player. He now has six fouls for the game and one foul is added to the team total.
