"We need to have a crack and see where it takes us. Yeah, we're a bit battered and bruised. It was quite a physical game and it's a six-day turnaround.
"The boys will have a light week this week and we really only get one ball-work session in, then the captain's run, which is a light run, and that'll do us."
Henry said he would take a wait-and-see approach with Roberts, who had a long history with knee injuries dating back to his time at Newcastle.
Rookie Cameron Cullen is on standby.
"(Roberts is) quite sore, posterior cruciate ligament strain, I think. He's had it before and it settles down quite quickly so it wasn't as bad as we first thought," Henry said.
"Cullo's done a good job there before. We'll wait and see. If he responds as quickly as he has done before, he'll be right to play."
The Titans can jump as high as sixth with a win, but can drop as low as 10th if they lose.
Henry's men finish the regular season with matches against the Wests Tigers (away), Newcastle (away), Penrith (home) and North Queensland (away).
