Juventus coach Andrea Pirlo delivered an injury update after their Champions League defeat at Porto.
Juve lost the first-leg of their Champions League round of 16 tie 2-1, suffering several setbacks over the game.
Danilo was booked and will be suspended for the second leg, while Giorgio Chiellini went off injured.
Pirlo said, “Matthijs De Ligt fortunately just had cramp. Chiellini has a calf problem and Morata wasn't in good shape before, then was sore at the end too, so we'll see. Morata hasn't been at his best since returning from a bout of flu. He was only playing tonight because we needed him.
“He felt ill in the locker room afterwards, he felt faint and needed a lie down, so he is not doing well."
