Sorry K'man, but you can't have had a very good view. Fev were in possession. Lussick accosted Bussey who was not in possession. Bussey pushed him away and Lussick just lost the plot. He landed at least 2 haymakers on the button and should have been red-carded immediately. Lussick will get a 2-3 match ban for this assault and someone else will benefit from his absence .
Having said all that I will also be surprised if Josh Hardcastle doesn't end up with some form of ban for the shoulder charge on O'Brien. But that was much later in the game by which time TW should have played for more than 3/4 of the game with 12 men.
