Folding the river for one is crazy, if you want to fold do it on the flop. It was 3 bet and capped behind you and you have one pair. Do you have outs? Yes. Do you know what they are? No. A jack gives the T9 straight draw the nuts and any overcard might beat you. You basically have to hope UTG+1 has 87, CO is overplaying his hand, and then you have to hit a 3. More likely CO has 88 or 77 and you have 2 outs. How often are the opponents capping with a worse hand, and how many outs do they have when they do? Fold the flop.
