Actually that was the look of Pierce about to whoop Kendall's arse all over the place. And Kendall will get fined heavily for headbutting Pierce with his helmet on and Pierce's helmet off.The only 'Skins' highlight was when Kendall ripped A. Pierce's helmet off. The look of fear on Pierce's face was well-captured by the camera.
It should've been Unsportsmanlike Conduct but the refs were clearly in the tank for the deadskins so I wasn't suprised no flag was thrown there.
