Already without sidelined Josh Bateman (shoulder) and Corey Horsburgh (foot), the Raiders lost Soliola to a facial fracture in the first half.

The veteran front-rower was rushed to hospital following a head clash with Dragons prop Blake Lawrie.

On Saturday morning the club confirmed Soliola would meet with a surgeon next week as he faces an extended stint on the sidelines.

"Sia's gonna be out for a period of time now. I think it's a lot of middles we're losing at the moment. It's an issue," coach Ricky Stuart said after the win.

The club has also confirmed an ankle injury for 22-year-old Guler, who exited the field late in the second half.

Scans are yet to determine the extent of damage or recovery period.

Winger Jordan Rapana also suffered a calf injury and is in doubt to play Melbourne in round nine.

Their crowded casualty ward means experienced forward Dunamis Lui is likely to be recalled for next week's crunch clash with the Storm.

It also means Stuart will have to rely on a host of inexperienced big men for the foreseeable future, including the likes of Ryan Sutton and Hudson Young.

Both were immense against the Dragons, with Englishman Sutton - in his second NRL season - especially targeted for rave reviews from his coach.

"Emre and Sutto did was exactly what was asked. It was perfect," Stuart said.

"That was probably Ryan Sutton's best game for us. Backed up with a young player in Emre doing that tonight was a wonderful start."

The Raiders, who now rise to fifth, were cruising at 22-0 after an hour before letting in the final three tries of the game and endure a scare in the final minutes.

However, their late collapse was of no concern to their coach, who said their gruelling travel schedule had worn his players out.

"I think we're the only team that has to go on the bus for three hours, get off and play a game of football," Stuart said.

"I've been very proud of how the boys have handled it, because they had to find a lot of energy there tonight in that last 20 minutes.

"We played extra time last week (against Parramatta). We didn't get home until last Sunday morning. We had a short turnaround.

"For them to back up tonight with all those injuries in the middle, showed the energy at the back end of the game. Why wouldn't I be happy?"
