The Stoke City centre-half has played once for England, in a friendly against Sweden in 2012, but is unlikely to be given another chance anytime soon according to Potters boss Hughes.
Despite his return to the Stoke line-up from a back injury coinciding with three Premier League clean sheets from as many matches, Hughes feels Shawcross may be too far behind the England defenders who have already staked their claim for Euro2016 under Roy Hodgson.
"Ryan Shawcross has had a long-term injury that he's just come back from and he's getting back up to speed," Hughes told Sky Sports News HQ.
"From the first time he came back against Chelsea (in the Capital One Cup) he's been outstanding. He certainly has the ambitions to get into the England squad but he just has to continue with performing well here.
"Roy has stuck with the players that have got him through the [Euro 2016] qualification campaign, however, so Ryan might have to wait for a change of circumstance in order to get a chance.
"All managers have loyalty to players that have produced for them in the past and you can understand that, particularly at this late stage before a major tournament."
