Cheetahs centre Benhard Janse van Rensburg received a yellow card on Saturday for a slide tackle on Leinster’s Fergus McFadden.
The South African slid along the wet turf at the RDS Arena to regather a loose ball in torrential rain.
The 23-year-old got the timing wrong and took out the legs of the Leinster winger before he reached the ball, resulting in a yellow card.
Leinster went on to win the game 36-12 leaving them top of Conference A in the Pro 14 table.
