The only justification I could think of, is that they didn't want to tip anyone off, by just YANKING him out immediately.
tip off the publich? i could not buy that one. it's not like we have a schedule of which games the refs are supposed to officiate.

do you mean tip off the mobsters? maybe, but the harm outweighs the good. we didn't tell you that the terrorists were going to bomb your home because we didn't want to tip them off. doesn't make sense, especially for playoffs. the league could just tell him that he didn't qualify based on too many bad calls.
