9d is a horrible card. Put him on a range and think about what kind of cards would (should) put enough heat on him and make him fold. If a FD is in his range than usually when it completes it's a bad card. When an undercard falls and we think he has TP then it's a bad card. Both of these are in his range making this a pretty bad card. If you think he'll call with FD two streets then you might have to be prepared to triple barrel him. You have to know what kind of suited cards he calls with because depending on the player an Ace could be a great card to double/triple barrel but if he's one to likely call with the nut flush draw on a T65 two toned board then the A will hit his range a lot. Again it all depends on ranges and if it hits more of their range as opposed to yours.

In this case I think a Kc and Qs would be a great turn/river combo which puts pressure on any one pair T and makes a lot of FD fold.
