South Sydney duo Jai Arrow and Cameron Murray have both been injured as the Rabbitohs came from behind to beat Gold Coast 46-28 at Robina.
Queensland forward Arrow is in extreme doubt for game two of the State of Origin series in Brisbane on June 21 after injuring his right ankle in the 21st minute and watching the second half on crutches and in a moon boot.
"We will see the damage when I get scans," Arrow told Fox Sports.
"(The ankle) feels really jammed up at the back and I did get told it is a syndesmosis but hopefully it is a minor grading. It is a bit disappointing, but happy we got the two points."
NSW forward Murray limped off with a groin injury in the 52nd.
He thought initially it was "a little bit of tightness" in his groin after backing up from Wednesday night’s Origin clash in Adelaide.
“I thought after five or ten minutes it would have warmed up but I got sorer during the game and there was a tackle where I stretched it," he said.
“I’ll just have to wait and see with scans. I hope it is not too bad.”
The Titans started on fire as they so often do to lead 12-0 inside 10 minutes and 22-16 at the break, but the Rabbitohs then piled on 30 unanswered points.
The Rabbitohs had a suite of players - including Campbell Graham, Keaon Koloamatangi, Damien Cook, Tevita Tatola and Cody Walker - in contention to be included in the Blues' side for the second Origin clash at Suncorp Stadium.
Most of them showcased brilliance but winger Alex Johnston scored a hat-trick to take his career try tally to 178 and outright fourth best of all-time after going past former NSW and Australia winger Brett Morris.
Walker and centre Isaiah Tass combined to send him over in the first half and Walker threw a pearler to put him in for his third.
The hosts have now lost five of eight games when they have led at the break and the trend continued in alarming fashion as the Rabbitohs put their foot down in the second half and the Titans fell apart.
“There are no excuses for it," Titans coach Justin Holbrook said.
The Rabbitohs had too much class.
Titans skipper Tino Fa’asuamaleaui was enormous off the bench after backing up from Queensland’s 26-18 win at Adelaide Oval.
But the big stories out of the night were the injuries to Arrow and Murray.
The Maroons will be without forward Tom Gilbert (dislocated shoulder) in Brisbane and with Arrow set to join him on the sidelines Queensland will have at least two vacancies in the pack.
Rabbitohs winger Richie Kennar was put on report for a late hit on Gold Coast No.6 Jayden Campbell.
Titans prop Moeaki Fotuaika was put on report for dangerous contact on Koloamatangi's leg early in the second-half.
Fa’asuamaleaui was unhappy with the decision. The Rabbitohs scored soon after through Johnston and never looked back.
