The Republic of Ireland international injured his back whilst getting out of the car, and the Potters assistant manager - Mark Bowen, explained to the newspaper exactly what happened:
“He did it, very simply, getting out of his car. People who have had bad backs will tell you how it can happen. He didn’t do anything untoward; he just got out of the car and felt something crack in his back. That was it. It’s the luck we’ve been having with injuries. Tell me about it."
Mark Hughes will be cursing his luck as his side's injury problems continue to mount. Jack Butland was recently ruled out for the season after injuring his knee on international duty, while the likes of Xherdan Shaqiri and Ryan Shawcross have only just returned to training following hamstring and back injuries.
Stoke will miss Whelan's tenacity, and ball-winning attributes in the middle of the park, as they look finish their season in style.
The former Sheffield Wednesday midfielder has played a key role in his sides impressive campaign. He has started every Premier league game, and provides a shield for the Potters back four.
His defensive discipline also provides a platform upon which Stoke's vast array of talented attackers can showcase their abilities.
The Britannia faithful will be hoping the injury isn't too severe, and Whelan is back in the first team sooner rather than later.
