( CNN ) -- Tiger Woods suffered a fresh injury setback Sunday after he was forced to pull out of the WGC-Bridgestone Invitational in Akron , Ohio , midway through the final round . Woods appeared to jar his back playing an awkward shot out of the bunker on the second hole . Evidently in some pain , Woods ' round deteriorated as he found both a pond and the trees before eventually deciding he could n't continue six holes later . By then he was four shots over par for the tournament . He was later seen struggling to get his shoes off , calling into question whether he will be fit for next week 's PGA Championship and the up and coming Ryder Cup . `` I just jarred it , and it 's been spasming ever since , '' he told the PGA 's official website . `` It 's just the whole lower back . '' Woods had only just recently returned to competitive action after taking three months out to have microdiscetomy surgery . The WGC-Bridgestone Invitational was his third tournament since the procedure , which was needed after Woods had struggled with the pain for close to two years . `` I do n't know , '' Woods replied when asked whether he would be fit for the PGA Championship . `` Just trying to get out of here .
