SYDNEY Roosters will bring in a debutant to cover the late withdrawal of halfback Mitchell Pearce for Monday’s clash with Penrith.

Pearce has been forced to withdraw hours before the game with a calf injury.

It means rookie playmaker Ryan Matterson will move off the bench into the halves, and NYC hooker Grant Garvey will make his NRL debut.

Garvey was pulled from the club’s under 20s side prior to their game and will be rushed onto the bench for the Roosters.

Penrith Panthers v Sydney Roosters, Pepper Stadium, 7pm (AEST) Monday

Panthers: 1 Matthew Moylan 2 Joshua Mansour 3 Waqa Blake 4 Tyrone Peachey 5 Dallin Watene-Zelezniak 6 Bryce Cartwright 7 Nathan Cleary 8 Leilani Latu 9 Peter Wallace 10 Suaia Matagi 11 Isaah Yeo 12 James Fisher-Harris 13 Trent Merrin. Interchange: 14 Moses Leota 15 Sitaleki Akauola 16 Christopher Grevsmuhl 17 Zac Hardaker

Roosters: 1 Blake Ferguson 5 Latrell Mitchell 4 Shaun Kenny-Dowall 3 Dale Copley 2 Daniel Tupou 6 Connor Watson 7 Mitchell Pearce 8 Isaac Liu 9 Jake Friend 10 Dylan Napa 11 Boyd Cordner 12 Mitchell Aubusson 13 Sio Siua Taukeiaho. Interchange: 14 Sam Moa 15 Aidan Guerra 16 Ryan Matterson 17 Kane Evans

The talking point: Penrith’s back three. They had a torrid time against the Warriors, coughing up a number of kicks that handed the Warriors prime attacking real estate. Mitchell Pearce and Jake Friend will have their radars honed with greasy conditions expected again, and the pressure is on the Panthers with the scramble for the top eight remaining as clear as mud.

The odds (courtesy of TAB): Panthers $1.55, Roosters $2.50

The Fox Sports Lab stat: The Roosters have the worst completion rate in the competition (71.7 per cent). They have the most incomplete sets inside their own half, averaging 3.7 per game. And not surprisingly make the most errors in the NRL, averaging 12.1 per game.

Our prediction: The Roosters to keep their late resurgence going and Penrith to be knocked off in a tight one.

Late Mail:Mitchell Pearce has withdrawn at the 11th hour with a calf injury. Ryan Matterson will move into the halves and Grant Garvey will make his NRL debut off the bench.

Te Maire Martin played NSW Cup on Saturday and won’t return to first grade this week.
