JJ monotone flop

What's your flop line here? I think the way I played it is very questionable. I couldn't decide how many outs to assign to my draw. All thoughts and comments welcome.

MP has loose/passive stats 45/4/0.7 after ~300 hands

CO has TAG stats 18/9/3 after ~450 hands. From what I had seen, his postflop was decent.
