Magpie defender Jason Cloke and Port defender were both booked on Monday morning for making contact with field umpire Michael Vozzo during Friday night's MCG clash between Collingwood and Port Adelaide.
They will front the AFL tribunal on Tuesday night, along with Bulldogs defender Brian Harris and Richmond defender Ty Zantuck.
Earlier this month, the AFL tribunal fined Hawthorn midfielder Adrian Cox $3500 for making contact with a field umpire.
