Gareth Bale will miss the second leg of Real Madrid's Copa del Rey fourth-round tie against third-tier Olimpic Xativa on Wednesday due to a calf injury.
Real boss Carlo Ancelotti said the Welshman had picked up the knock in training on Tuesday, but was hopeful he would be fit for Sunday's trip to Valencia in La Liga.
"He had a little problem with a knock on his calf and we'll need to see how he recovers over the nest few hours, but I don't think he will have any problems in playing on Sunday," said the Italian.
Madrid will also be without the suspended Cristiano Ronaldo and Los Blancos still have work to do to seal their place in the last 16 after being held to a 0-0 draw in the first leg.
Ancelotti's men also suffered a blow to their La Liga title hopes with a 2-2 draw away to Osasuna on Saturday that saw them fall five points behind Barcelona and Atletico Madrid.
And the former Chelsea boss wants his side to recreate their fine start to the match in Pamplona at the weekend.
"We need to continue in this competition, it is important for us.
"We need to play well and with intensity. We didn't play badly at Osasuna, although the result wasn't great. The first 20 minutes were the best we have played this season."
