Winger Brett Morris says the Dragons have to negate the influence of Tigers young guns Luke Brooks and Mitchell Moses in Sunday’s NRL clash.

St George Illawarra will zero in on Wests Tigers young guns Mitchell Moses and Luke Brooks in Sunday’s round 20 clash at ANZ as the joint venture bid to keep their flagging NRL finals hopes afloat.

Monday’s loss to ladder leaders Manly has pitched the Dragons behind the playoffs eightball to the bottom of the logjam of teams fighting it out for a finals berth over the final seven weeks of the regular season.

Brooks and Moses were instrumental in the Tigers’ upset 46-18 thrashing of Canterbury last start and a win for the joint venture will thrust them into the top eight at the end of the round, following Brisbane’s 30-8 loss to Melbourne on Friday.

Caretaker coach Paul McGregor believes the Dragons have to win four of their past seven to feature in the September action, but with their poor for and against only five victories will likely guarantee them a playoffs berth.

That makes the clash with the Tigers crucial and winger Brett Morris believes shutting down youngsters Moses and Brooks is the key to victory.

“They were pretty slick last week, they are a pretty young side with the half (Brooks) and the fullback (Moses), they are young fellows, very enthusiastic and they keep you on your toes,” Morris said.

“They played some great footy together last week, so we are going to have our hands full.

“They are very enthusiastic and that is one thing we certainly have to match … the Tigers side this year has blown other teams off the park.

“So we are going to have to be very wary of that and Aaron Woods has been carrying them forward very strongly.

“They have threats all over the park so it is going to be a tough job.

“We have a short turnaround and sometimes that is the best thing for you after a loss, that loss hurt us and we need to get back into the winners list.

“We still have a few things to fix up if we want to make a charge to the finals and we have to put in a better performance against the Tigers.”

The loss to Manly at Kogarah was Morris’ first match back since fracturing his shoulder in a heroic effort in NSW’s epic win in State of Origin I in late May.

The 27-year-old Australian representative said his shoulder has recovered better than expected.

“The shoulder has pulled up really well,” he said.

“I was looking at a round 21 return but was back early which was pleasing.

“I have to strap it which is something new but it is fine.”
