Diego Carlos was sent off in Aston Villa's friendly defeat by RB Leipzig in New Jersey.
The Brazilian defender was dismissed after two yellow-card offences in the first half as Villa lost 2-0 to their German opponents.
Carlos, who joined Villa from Sevilla in 2022, was booked for separate altercations with Leipzig goalscorer Lois Openda.
Andre Silva also scored for Leipzig, with both goals coming before half-time.
Villa boss Unai Emery, who lost Sweden goalkeeper Robin Olsen to injury, preferred to focus on the performance of new signing Amadou Onana rather than Carlos' red card.
