The Potters face Croatian outfit Hajduk Split in their opening Europa League clash at the Britannia next Thursday.
But the injury-prone former England centre-back, 31, will not be rushed back into action.
Stoke boss Tony Pulis said: "He wants to get going.
"He's had two or three good days' training but he has still got some strength work to do.
"It will be interesting to see how he does because we are hoping he will be a good, experienced player for us."
