Willy Boly will have further tests this week after the Wolves defender reported an elevated heart rate that ruled him out if the derby draw with West Bromwich Albion.
Boly was also said to be suffering from extreme fatigue that left him unable to train properly last week, and Wolves hope more checks this week will shed further light on the problem.
Wolves boss Nuno Espirito Santo revealed that some of his players who have contracted Covid-19 – there have been at least 10 over the course of the season – have felt effects some time after leaving isolation.
