Jack and O'Connor were at each other just before the first goal, but the TV cameras didn't seem catch it (I went back to the recording when I got home to try and see what kicked it off). There was a bit of shouting then they squared up to each other. Taylor and Hayes got between them and split them up, but they were still having a go at each other. No idea what started it, but I thought it knocked the concentration of Taylor and O'Connor afterwards.
