Pereira grabbed a second-half four-pointer in the 20-8 win but found himself on report for a high shot that cost the Titans new recruit Corey Thompson for the remainder of the match.

The grade three charge carries a base penalty of three game on the sidelines, though it can be reduced to two with an early guilty plea.

Should the club take that option, it leaves the door open for Saab to make his first appearance of the season after the club knocked back multiple requests for a release from the 19-year-old's management.

It's sparked fears of mass exodus, with Issac Luke released to link with Brisbane last week and James Graham expected to follow him out the door to link with St Helens.

The club has denied separate reports that Tristan Sailor, who'll also come into the selection frame if Pereira's rubbed out, has also asked out of his deal as players fac frustrating weekends on the sideline if they miss the 17 in the absence of a reserve grade comp.

Saab has warmed up in kit the past two weeks as 18^th man and will likely get his first shot against the Roosters after scoring three tries in three games last season before suffering a broken foot.

He also underwent off-season shoulder surgery that limited his preseason but remains under contract until the end of 2022 alongside Mikaele Ravalawa, who this week recommitted for three more years.

While Saab's chomping at the bit to get on the park, doing so against the Roosters will be a daunting task after the defending premiers outlasted Parramatta 24-10 in a blockbuster on Saturday.

The Dragons have won two on the trot but will start rank outsiders, with Paul McGregor saying his side will need a vast improvement to test their traditional rivals.

"They're playing a good brand of footy, and exciting brand of footy and they apply pressure through how hard they attack the ball," McGregor said.

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

"It's about us really making sure that we reverse that and apply a bit of pressure to them. They're a very good football said, they're dual premiership-winners, and they're playing the game at speed which is what it needs to be played at."
