Valencia will be without midfielder Manuel Fernandes for the remainder of the season after he fractured his shin against Getafe.
The former Everton man played the whole 90 minutes of Sunday's 4-1 win at the Mestalla despite feeling a sharp pain in his ankle just 15 minutes into the contest.
The bone fracture was discovered after a medical examination on Monday morning leaving Fernandes baffled as to how he was actually able to complete the match.
"The truth is that it hurts a bit, but I was able to play comfortably," said the 23-year-old.
"Now, after knowing what happened to me, I don't know how I could stand. Clearly I'll miss the rest of the season."
Valencia doctor Antonio Giner has explained how Fernandes was able to carry on, telling the club's official website: "He has a large muscle mass that held the bone in place, and in his case the shin is not heavily loaded."
