It would have been his second flagrant. This is an automatic ejection. Seen it a few times now, and because I favour aggressive players I probably see this more often than most. Its happened to me four times now I think, so its not exactly a common occurence.
I know in the past the name of an ejected player would turn from black to mauve. Seems like they got rid of it for whatever reason.
That's a shame. That should be brought back.
