Andy Wilkinson could miss Stoke's final four games of the season after being sent for a scan on his hamstring injury.

The full-back limped out of the Potters' 3-0 defeat at Newcastle with the problem and is now undergoing tests to ascertain the full extent of the damage.

Pulis is waiting on the results and has urged caution on whether he will feature in the run-in to the season, especially as Wilkinson only just returned from a two-game absence when playing at the weekend.
