Should the referee have stopped the Usyk - Fury match earlier?

Ukrainian boxer Oleksandr Usyk almost knocked out British Tyson Fury in the ninth round, in the fight of the century held on Saturday night. 

After a flurry of shots from Usyk, Fury was very close to being knocked down, but the referee stepped in and counted Fury while he was still on his feet. Fury managed to sing and then the gong saved him. The fight went to 12 rounds, and Usyk won by points and became the undisputed heavyweight champion. 

Many have estimated that the referee was wrong and that Usyk should have won by technical knockout in the ninth round.
