Preston boxer Scott Fitzgerald was a bystander as former world welterweight champion Amir Khan and future opponent Phil Lo Greco clashed at a press conference.
The Jennings Gym ace is due to fight on the undercard of the blockbuster bout, which is scheduled for April 21, at Liverpool Arena.
On the top table, Fitzgerald had a ringside seat as Khan reacted to taunts about his personal life by throwing water over Greco
Khan is returning to the ring for the first time in almost two years after a period of well-publicised marital difficulties as well as a spell in the 'I'm a Celebrity' jungle.
Lo Greco, who has won 28 of his 31 fights, mocked Khan's career trajectory, insisting he had been on a "losing streak" in and out of the ring since losing his last fight against Saul Alvarez in May 2016.
Khan responded by splashing water towards Lo Greco at the Liverpool press conference, prompting security to intervene before Khan insisted he would take the bout as seriously as ever.
Khan said: "I will train like it's a world-title fight. Greco says maybe I'm past my best. I'm 31 and at the peak of my career.
"For me, boxing is the way forward. Boxing put me here and I am going to finish on a high."
Cynics may suggest Khan's antics were designed to reignite his public profile since his signing with promoter Eddie Hearn, who has made no secret of his desire to make a domestic super-fight against welterweight rival Kell Brook.
Brook returns to the ring for the first time since he lost his IBF welterweight title to Errol Spence last year when he faces Sergey Rabchenko in Sheffeld next month.
Khan insisted: "I have a great three-fight deal. To start in Liverpool, a great city, this will be another big one. He has just motivated me to go to the gym and work hard. I am going to give this guy a beating for 12 rounds."
Fitzgerald, meanwhile, looks set to fight a 10-rounder with a title possibly at stake. His opponent is yet to be confirmed.
The 26-year-old will also appear at the Victoria Warehouse, in Manchester, on February 25, which will act as a warm-up bout
