Brodkin was handed a caution from the court for invading Everton's Goodison Park pitch dressed as his footballer alter-ego Jason Bent.
The comedian began training with the Manchester City players while wearing their team colours before getting spotted by stewards and led away from the pitch.
"I've been told absolutely not to do any more," Brodkin told The Sun. "My management and my family have asked me not to."
While Brodkin works as a comedian, he is also a qualified doctor.
