Manager Tony Pulis has revealed the Jamaica international suffered no fracture when he sustained the injury 14 minutes after coming on as a substitute for Salif Diao.
This means he will not be facing a lengthy spell on the sidelines, although the club have yet to confirm how long he will be missing for.
When Fuller dislocated his left shoulder at Sunderland two seasons ago, he was back within 10 days and only missed one Premier League game in that period.
His absence may be limited this time by an international break which means Stoke do not play for two weeks after Saturday's match at Blackburn.
