Elderly residents at Broadacres Care Home, on Naylor Street, were delighted to see the furry football mascot walk through their door.
Miller Bear took a tour of the home to meet the residents, staff and visitors and take photos.
Diane Rice, activities coordinator of Broadacres Care Home, said: “Hug a Bear Day might be one of the more unusual national celebrations but when your local football mascot is Miller Bear it would be a shame to miss it.
“Our thanks go to Rotherham United FC for releasing Miller Bear for the day so he could come and see our residents.
“They were absolutely delighted by the visit and couldn’t resist a hug with the giant bear.”
