Walters appeared to receive an unintentional elbow in his face from West Brom defender Gareth McAuley in Saturday’s 1-0 defeat for the Potters at the Hawthorns.
“It looks like he might have a fractured cheekbone said Stoke boss Mark Hughes post-match.. He’ll have to have it checked on Monday, hopefully it isn’t too serious. But that’s the worry at the moment so obviously he had to come off.
I just think it was a challenge in the box, I’ve not seen it again. I don’t know if it was arms or heads coming together or what’s occurred but he’s got a bang on the side and there’s a bit of a depression so it looks like it might be a fracture.”
The 31–year-old forward played in the Euro 2016 qualifiers against Scotland, Germany and Georgia and in current form Walters was expected to be selected to start against Poland. The former Ipswich man has scored ten goals in 30 appearances so far this season playing up front or wide.
West Brom boss Tony Pulis masterminded a victory against his former club as the Baggies edged out lacklustre Stoke on Saturday. Brown Ideye headed the decisive goal early on but the hosts could have had more in a dominant display that lifts them 11 points clear of the drop zone.
The visitors, whom Pulis managed from 2006 until 2013 and moulded into an effective Premier League outfit, failed to muster a clear chance.
