New Wolves boss Bruno Lage will make his debut against Crewe.
The trip to Gresty Road on Saturday, July 17 is being treated as a first-team match, says the Express & Star.
The clash is set to be the first one of pre-season, with training beginning at Compton on Monday, July 5.
Lage's line-up will depend on when some players come back from the Euros, but it is expected to be made up mainly of senior players as the former Benfica chief looks to get his philosophy across.
Wolves are then thought to be looking into travelling overseas as they continue their preparations for the 2021/22 term – as long as government guidance allows them to do so.
The trip could involve a friendly against a foreign team as well.
