JJ flops overpair against an overbet and call

[paperboyNC]

UTG is 27/5/5 (VPIP/PFR/AGGR) after 150 hands
Button is 43/5/0.5 after 30 hands

Empire Poker No-Limit Hold'em, $0.50 BB (6 max, 6 handed) converter

MP ($12.10)
CO ($21.45)
Button ($52.95)
Hero ($59.45)
BB ($56.65)
UTG ($60.05)

Preflop: Hero is SB with J[img]/images/graemlins/diamond.gif[/img], J[img]/images/graemlins/heart.gif[/img].
<font color="#CC3333">UTG raises to $2</font>, <font color="#666666">1 fold</font>, CO calls $2, Button calls $2, Hero calls $1.75, BB calls $1.50.

Flop: ($10) 3[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/diamond.gif[/img], 5[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(5 players)</font>
Hero checks, BB checks, <font color="#CC3333">UTG bets $9</font>, CO folds, Button calls $9, Hero ?

The key number I'm noticing is UTG's 5% PFR and his pot size bet on the flop (very rare at this limit). Do I raise, fold or take a card off?
