Misconduct yes - a lot of the shouting came after I'd shown the red card, plus he had another go at me as we were walking back to the changing room, so I put in two extra reports.
Abandonment I decided against. Once he left, two of his teammates came up to apologise for him, I had NAR's so felt a little safer with them around and as there were only 2 mins left to play in added time and it was 4-1, I thought that abandoning was likely to cause more trouble than just playing out a notional minute or two.
