Holbrook fears for Corey Thompson's jaw

The Titans held concerns for new signing Corey Thompson's jaw in the aftermath of the 20-8 loss to the Dragons on Saturday.

Thompson left the field in the first half in a daze after being hit high by Dragons winger Jordan Pereira.

He is one of three Titans under an injury cloud ahead of next Saturday night's clash with the Broncos with Phillip Sami (hamstring) and Young Tonumaipea (knee) also leaving the field in the second half.

There was some confusion as to why Thompson had not returned in the second half but Titans coach Justin Holbrook said it was due to the fullback failing his HIA.

"Corey has some issues with his jaw. Hopefully he is alright. That makes it hard when you lose your new fullback after 20 minutes to foul play," Holbrook said.

"Phil, I am not sure about, and with Young I don't think he will be right. He has a knee issue.

"It was tough. We were never good enough. We did well to keep the score to what it was. It flattered us."

Holbrook said bench utility Tanah Boyd was a "livewire" in attack and was the side's best with the ball.

Boyd will come into contention for a starting spot next week as will halfback Tyrone Roberts who is set to return from an ankle injury.

"He is pretty much right now. He hasn't been able to train 100 per cent since pre-season in November," Holbrook said.

"Ideally I'd love to give him four weeks of training but I might have to bring him back next week."

For Dragons coach Paul McGregor it was a win to savour and took the Dragons to 11th spot on the ladder and just outside the top eight. The early power of NSW prop Paul Vaughan and the impact of his front-row partner Josh Kerr gave the Dragons much needed momentum through the middle.

Halves Corey Norman and Adam Clune, along with fullback Matt Dufty, all had a hand in Dragons tries in a sign the spine is starting to fire.

"We've gone back-to-back but there is definitely improvement in us. When we build pressure we score points and most importantly today, when we conceded set-on-set, we defended it," McGregor said.

"There is a lot of improvement left but the good thing is when you are not playing at your best and you are winning.

"I thought Vaughany started the game really well. Kerry is still learning his trade and he finished his stint better than he started. He will continue to improve."

McGregor knows his side must lift several gears in attack and defence to compete with the Roosters next week.

"They are playing an exciting brand of footy and they apply pressure through how hard they attack the ball," McGregor said.

"They attack the space well and have people moving and after that they get their line going really hard at you and force you into uncomfortable situations.

"It is going to be about us making sure we reverse that, and apply a bit of pressure to them."
