The river's a pretty clear fold for me. A villain can't be expecting to call you down and push you off high cards here, so the river bet by villain reeks of one that wants to be called. Occasionally you'll be bluffed out of this pot by a missed draw, but I don't think that comprises enough of his range on the river to warrant a call. Additionally the board texture isn't appropriate for a free card on the turn. You can too much to gain by betting, and your marginal hand has a lot to lose by giving a free card (most hands have 6+ outs against you).
