Three men, two of them the sons of a prominent QC, have struck a deal with prosecutors that could see the most serious charges against them over a vicious post-AFL match bashing withdrawn.

Brothers Dominic and Sam Walker, aged 28 and 25, and friend Benjamin Fitt, 28, have indicated they will plead guilty to viciously bashing two men after an AFL final on September 7 last year.

But their lawyers told Melbourne Magistrates Court on Tuesday their clients would only plead guilty if the majority of the charges against them were dropped.

The Walker brothers are the sons of Tim Walker, QC, and grandsons of pre-eminent scientist and 2000 Australian of the Year recipient Sir Gustav Nossal.
