Jai Arrow looks to be a certain starter for the Titans after the side had its' final session before the Round 19 clash against the Knights.
Arrow missed last week's match due to knee complaint but got through training this morning.
"At this point everyone seems to be fine so 1-18 will travel," Brennan said.
If he (Arrow) gets through training, we'll be 1-17. I'm confident, he said it feels really good. He should get through ok.
"Jai is a massive part of our team. He's been one of, if not, the best in our team this year."
Another player coming off a heavy workload the past few weeks is AJ Brimson, but Brennan believes he's up to the challenge.
"I hope he keeps building his confidence and takes a bit of pressure off Ash. I need AJ to step up and take some pressure off him. I need that from everyone.
"He did it last week and kicked a bit more. We trained without Ash at the start of the week and he took more control so we should see it a bit more from him."
