This was a poor decision that could have proved very costly for Hull City.
Oumar Niasse received a very soft red card during Hull's game at home to Watford.
Of course, referees don't have an easy job, and everyone makes mistakes, but Bobby Madley appeared to make a clear error here.
Niasse, who is on-loan at the Tigers from Everton, went for a loose ball with Mbaye Niang. The Watford forward got there first, and Niasse made contact with his opponent's shin.
It was a late challenge, but there appeared to be little contact, and definitely not enough for a red card.
However, Madley sent Niasse off, much to the shock of the striker, his teammates, his manager and the Hull fans.
We're not allowed show you video footage of the incident, but here's how it played out:
Niasse's reaction said it all.

Luckily for Hull, who are in 17th position in the Premier League, just outside the relegation zone, they went on to win 2-0.
Swansea City, who are two points behind Hull, won their game 2-0 on Saturday afternoon against Stoke City.
