Anthony Joshua has warned Kubrat Pulev that Saturday's world heavyweight title fight could be over quickly.
The pair had to be kept apart on a number of occasions during Friday's heated weigh-in, with the WBA, WBO, IBF and IBO holder booed by the Bulgarian's entourage before he stepped on the scales.
Concerns this bout at Wembley's SSE Arena may fail to ignite have been allayed and the Briton is eager to bring back his ruthless streak.
The 31-year-old won his first 20 fights inside the distance, but his last four have brought two victories on points and the notable shock loss to Andy Ruiz Jr in June, 2019.
Trainer McCracken was criticised 18 months ago after Joshua lost his undefeated status at Madison Square Garden, but did help mastermind a disciplined display in the rematch with Ruiz in Saudi Arabia.
It saw his fighter return to the top table of heavyweight boxing and while bigger and more lucrative bouts should lay in wait, there is still a job to do.
McCracken said: "He's got to be disciplined from round one. Hopefully he gets into a nice rhythm, he starts to box well, then by the middle to late rounds he can start to put things together and look what he is, which is a great fighter."
McCracken did not go as far as to say the F-word, Fury, had been banned in camp this week, but stressed it was one opponent at a time.
"Anthony Joshua's ready for anybody," he said. "But Pulev is a good and dangerous fighter so get Pulev out of the way then the sky's the limit."
