Wolves boss Julen Lopetegui says Matheus Cunha will need an MRI scan after he suffered an ankle injury in Wolves' draw with Fulham.
Cunha received treatment on the pitch for several minutes before trying, and failing, to walk off the pitch. A stretcher was then required to take him off the field.
Now, Lopetegui has confirmed it was an ankle injury and that the forward will need tests tomorrow to determine the damage.
He said: "We have to wait for tomorrow. Tomorrow there will be an MRI and we have to wait for that check."
