Manchester United forward Antony is not expected to be out for a lengthy period.
The Brazilian was not available for their home game against Leeds United on Wednesday.
The Red Devils drew the contest 2-2 at home in the Premier League, with Leeds taking a 2-0 lead in the game.
"I don't know. I don't think it is a long time but we have to see how it develops in the coming days," Ten Hag said about Antony pre-match to reporters.
"It is in his leg, but I can't specify. You will understand that."
A bit of good news for United was the return of Jadon Sancho, who scored their equalizer in the game.
