Yup. SB could have any PP or even a hand like A4. Yu showed no strength on the flop (presumably hoping for a safe turn card to raise)...of course you see one of the worst possible turn cards but I think given your flop line you are committed to calling down (9:1 is almost enough to draw to full house even if we assume SB has a flush and limper is drawing to one). Worst hand SB could have would be one with a 7 but wouldnt SB gone for c/r on flop with a 7? I'd call turn and call 1 bet on river unless it is a non-9 heart.
