Tottenham Hotspur are hoping defender Jan Vertonghen does not have a serious injury after he took a knock to his ankle in training.
The player was expected to start against Crystal Palace but missed the game with the issue.
And manager Mauricio Pochettino revealed the club would assess any damage done tomorrow.
"Jan we need to assess tomorrow. He received a heavy knock on his ankle," he said.
"We were training yesterday and we couldn't not communicate because we were waiting until the next day to assess him to see whether it was possible to play him.
"He wasn't ready, but now we need to see. We hope it's not a big deal."
