The Sun reports Perez had to be restrained by his Newcastle team-mates and coaches after blowing his top at ref Jeremy Simpson.
The Toon striker was denied a stonewall penalty in the dying moments of his side's incredible 3-2 Carabao Cup defeat to Nottingham Forest.
It was 2-1 to Forest in injury time when home keeper Luke Steele clearly wiped out Perez in the box after the Spaniard nodded the ball.
Forest then went on the attack and grabbed a crucial third goal through Gil Dias' strike.
At full-time Spaniard Perez had to be pulled away from Simpson by two of his coaches and team-mates Mo Diame and Ki Sung-yueng as he vented his anger.
