Watch Hildeberto Pereira set up Henri Lansbury’s late equaliser and then see red after celebrating with the crowd.
Pereira was lost in the moment as Forest salvaged a point against Aston Villa in the dying minutes, and was shown a second yellow card after going over to the travelling Forest fans.
The Portuguese, 20, had been booked moments before after confronting Villa defender Aly Cissokho.
Forest's equaliser came through some great work from Pereira, who played a clever one-two before finding Lansbury, whose tidy finish with the outside of his foot sailed past Mark Bunn in the Villa goal.
Apostolos Vellios had put Forest ahead with a stunning 25-yard strike, but Villa then took the lead after goals from Ross McCormack and Rudy Gestede.
Forest's opener came from a quick counter, and Vellios picked the ball up from 25 yards out before unleashing a powerful effort which was too strong for Mark Bunn.
The spoils were ultimately shared in a game which saw two former European champions face each other outside the top-tier for the very first time.
