Definition of phantom punch in English English dictionary
A punch of the fist that is not real, for whatever reason, to which there is a reaction as though it were, such as the final blow, according to ringside spectators who did not see it, in the 1965 rematch between Muhammad Ali and Sonny Liston
In only his second defense he took on Mike Tyson and found himself on the losing end of a very questionable first-round knockout. (It seemed he was dropped by a phantom punch.) That was Seldon's last fight.
