He clipped him late. Yellow card. Can't go from a red to a yellow.
Sorry Tegal, but he was given a straight red card not a yellow. Ref also spoke to the Roar captain after the game and he acknowledged his error. That is why he got off. I watched the game and could not believe the refs decision.
From what I saw on the highlights, I wonder if he confused Paartalu with Broich.
That was my first reaction as well.
