Manchester United forward Antony was taken off on a stretcher after sustaining an injury during the first half of his team’s Premier League game against Chelsea on Thursday.
The Brazil international looked in distress as he left the field at Old Trafford in the 29th minute, raising concerns over his availability for the FA Cup final against Manchester City on June 3.
“I can tell you that it’s serious but we have to wait minimum 24 hours and then we know probably more about the status of his injury,” United manager Erik ten Hag said.
Antony — a $95 million signing from Ajax last summer — held his face as he was carried off, and Ten Hag consoled him with a pat on the stomach before he was taken to the locker rooms.
It was not immediately clear what part of the body Antony hurt, but he went down after a challenge from Chelsea defender Trevoh Chalobah and was replaced by Marcus Rashford.
United is already without Lisandro Martinez and Marcel Sabitzer for the cup final. Luke Shaw is also a doubt after coming off at halftime in the 4-1 win over Chelsea which secured a Champions League place for United.
