Technical - Ejection

[billyc8037]

JV Boys Game in Massachusetts. (not that it really matters where) The game is in OT with a few seconds left on the clock. Team A is down by 1. A1 drives the lane, goes up for the lay-up, makes the shot, draws the foul and when he lands, hits the official in the face who was bending down under the basket to pick up the ball upon blowing the whistle for the foul against B1. Official regains his composure (or not), is obviously pi$$ed off for being hit by A1, calls a technical on A1 and ejects him from the game. Team A coach must now replace ejected A1 with another player in order to complete ejected A1's single foul shot. A2 fails to make the single free throw. Team B produces a player to shoot the two technical shots and B1 makes both winning the game. A1 inadvertently came down on the ref with no malice, intent or deliberation. Was this the right call? should the "T" have warranted an ejection?
