Ross Moriarty has revealed he thought it would be "the end of me" had referee Jaco Peyper sent him off in Wales' World Cup quarter-final against France.
Moriarty had only been on the pitch for 90 seconds, replacing an injured Josh Navidi, when he was yellow-carded for a high tackle on Les Bleus centre Gael Fickou.
Wales went on to triumph 20-19, with number eight Moriarty scoring the winning try - but only after an incident that left him sweating, especially when Peyper called in captain Alun Wyn Jones.
I was just thinking, 'please, please don't be a red'. I knew how bad that would be for the team. I've been in that situation before, and it is not a nice feeling.
Moriarty has similarly vivid memories of his match-clinching touchdown, which followed a concerted spell of pressure near France's line.
I was running towards the ball and just thinking 'I can't mess this up'. I didn't even want to reach out in case someone came from nowhere and kicked the ball out of my hands, so I just landed on my head first and got the ball under my chest to make sure no-one could come in and get it.
Moriarty is set to take hamstring injury victim Navidi's place against semi-final opponents South Africa on Sunday.
This is a game I look forward to. I know what their forwards thrive on, which is being physical, and that's what I thrive on as well. Some players go hiding when it gets tough, but I think I get better in those situations.
