Antony had to be stretchered off midway through the first half against Chelsea after suffering an serious-looking injury.
The Manchester United winger went down following a tackle from Chelsea defender Trevoh Chalobah. No foul was given by the referee, but United put the ball out of play so Antony could receive treatment.
The Brazilian appeared to be in a considerable amount of pain and was substituted for the returning Marcus Rashford. He went down clutching his foot, which appeared to get stuck in the ground as Chalobah made the tackle.
