Wolves' Europa League match at Olympiakos on Thursday will take place behind closed doors as part of coronavirus measures.
The Greek government has enforced a temporary suspension of spectators attending sporting events due to the Covid-19 outbreak.
On Monday, the number of confirmed coronavirus cases in Greece rose to 73.
Nuno Espirito Santo's side are set to take on the Greek top-flight leaders on Thursday in the last-16 of the Europa League at Karaiskakis Stadium in Piraeus, near Athens.
Wolves explained in a statement Olympiakos had "sought clarification" whether their fixture would be affected by the sporting event suspension to run from March 9 to March 22, and were unable to stage the contest as normal.
"Unfortunately, the decision has now been confirmed and all parties must submit to the official ruling imposed by the relevant Greek authorities," Wolves said in a statement.
"We share the disappointment of all of our supporters who will be affected by this decision, and can confirm that all match ticket refunds will be processed over the next 48 hours.
"Refunds will be made using the original payment method, and any supporters who purchased in person and paid with cash will be contacted by Wolves ticket office staff to arrange a refund."
One thousand tickets had been sold by Wolves for the match in Greece and the return fixture at Molineux is due to be played on March 19.
