Peter Lalor, senior cricket writer for the Australian newspaper, told BBC Radio 5 live: "He looked stunned, put his head down, we assumed he was going to shake it off but he fell sickeningly into the pitch, his hands didn't come out to break his fall, and then we knew it was pretty serious.
"Possibly the worst part of it was they had to give him mouth to mouth in front of the members' stand because he wasn't breathing.
"He is one of the most respected and liked kids in Australian cricket, he doesn't have an enemy in the game, he's great company.
"I was there when he played his first Test. Phil and I talk quite a lot and we were chatting in the UAE about him playing and said to him he would probably get Alex Doolan's place and he said 'I don't want it, I don't want to see that done to Dools, he's my mate'."
