Brentford striker Neal Maupay was booked while still a substitute during victory at Chelsea.
Maupay was shown a yellow card for interfering with a Chelsea free-kick. The Frenchman kicked the ball away from Cole Palmer, which led to him being shown a yellow card.
The striker eventually came on, despite being on a booking, and had the last laugh on Palmer.
Maupay set up Brentford's second goal, scored by Bryan Mbeumo, as the Bees ranout 2-0 winners on Saturday.
