The MRP assessed an incident where Hall appeared to punch O’Brien in the chest or throat during the third quarter of the Bulldogs’ heavy loss to the Magpies, but it was determined that not enough force was used to warrant a report.
However, Hall faces a $2600 fine for using abusive language towards umpire Matthew Nicholls during the second quarter.
With an early guilty plea he can have the sanction reduced to $1950.
Hawthorn’s Shaun Burgoyne faces a one-game ban for engaging in rough conduct against Fremantle’s Alex Silvagni at Subiaco Oval on Saturday afternoon.
Even with an early guilty plea, the penalty remains at one game.
It means Burgoyne will miss round one of the 2011 season unless he contests the ban at the tribunal and has it overturned.
