on20s,
First think about what types of fouls are grounds for suspensions. Those are fouls that somehow result in red cards, albeit straight or accumulation of yellows.
With that as a frame of reference, please explain to me how video could incriminate one player and not afford the opportunity to defend his position. It's really very simple, did (or in this case, should have resulted) the foul result in a red card, answer yes. It doesn't matter what was going on between players up to that moment.
(With that said however, I would hope that the league officials reviewed the entire video to at least get a feeling of the flavor of the match.)
