Newcastle United midfielder Miguel Almiron was sent off just seven minutes after coming on in Paraguay's friendly against Mexico for an "awful" challenge.
Almiron was given a straight red card after going through the back of Jose Juan Vazquez, with his studs raking down the back of the Mexico midfielder's calf.
The match in California pitted Almiron - who became Newcastle's record signing in January - up against his former Atlanta United boss Gerardo Martino, who was taking charge of Mexico for just the second time.
Almiron had been sent on with Paraguay 3-0 down, but after quickly registering an assist for a Hernan Perez goal, he was given his marching orders just three minutes later.
