Manchester United manager Erik ten Hag admits Antony has suffered a "serious" injury that could rule him out of the FA Cup final.
The 23-year-old was carried off in the 29th minute of United's 4-1 victory over Chelsea after a fair tackle by Trevoh Chalobah.
Antony appeared to be in tears as he received treatment and he attempted to continue but required the aid of a stretcher nine days before United face Manchester City at Wembley.
