Watford midfielder Domingos Quina is set to miss game time due to a groin injury.
The Portuguese star came off early in the game, as he picked up the injury against Everton on Tuesday night.
His manager Quique Sanchez Flores said the player was unlucky to get the issue, and hopes that he will be back soon.
"He was unlucky because he slid on the pitch and he felt something at that moment," he told reporters.
"It is completely unlucky for him and completely unlucky for the team with him because we are really happy with him and he's a very good player for us.
"I think the medical staff will check the player tomorrow and we will see what happens."
