Danny Ainge said that Bird was also telling Dr J it was time to retire. Also one of the refs had broken his leg earlier in the game, so there's only one ref at the time this happened.
Doesn't seem to be much hard feelings afterwards. Dr J. had this to say about Bird for a tribute.

Check out this clip I just saw.. Larry Bird deliberately showing Red Auerbach bad shooting form still hits nothing but net.
