Under no sircumstances should a fight be delayed to watch a replay. However in the time between when the fight is halted and when the decision is made, there can be an official reviewing the tapes to make sure of the cause of the cut. Then make a ruling based on what he saw.

The doctor stopping the fight should be irrelavent of the cause. And if a corner asked the dontor to check on his boxer and the doctor stops the fight. Then the tape showes the cut was from a punch. It should be ruled a TKO. The corner can't go back and say "but I though it was from a head but".
