Stoke City keeper Jack Butland says a scan on his ankle show he has aggravated a previous injury.
The England international was ruled out yesterday after picking up a knock in training.
He had been due to make his return to the Potters first team after fracturing his ankle in March.
Great news from my scans, ankle is solid but I've damaged some scar tissue which is giving me the pain, will settle down quick, back soon ??— Jack Butland (@JackButland_One) August 13, 2016
