TT facing big aggression

i have played only 30 hands with utg. he's been on the rocky side(7/0/0).
CO is 32/17/1.8 after 70 hands.

Preflop: Hero is BB with T[img]/images/graemlins/spade.gif[/img], T[img]/images/graemlins/club.gif[/img].
<font color="#CC3333">UTG raises</font>, <font color="#666666">4 folds</font>, <font color="#CC3333">CO 3-bets</font>, <font color="#666666">2 folds</font>, Hero calls, UTG calls.

Flop: (9.50 SB) 3[img]/images/graemlins/spade.gif[/img], 8[img]/images/graemlins/heart.gif[/img], 9[img]/images/graemlins/heart.gif[/img] <font color="#0000FF">(3 players)</font>
Hero checks, <font color="#CC3333">UTG bets</font>, <font color="#CC3333">CO raises</font>

my initial plan on the flop was to c/r CO's continuation bet, trying to get it heads-up with him. but now that utg donks and CO raises, what's the plan?
