Under 20s Coach Adam Hartigan has been forced into a reshuffle of his side after injury saw the withdrawal of one of our Holden Cup squad's biggest names.
Already without NSW Under 20s backrower Jakiel Mariner, Hartigan has now lost halfback Jackson Hastings due to a broken wrist.
Vice-Captain Tyler Cornish will shift to halfback in Hastings' absence, with Alex Lyons promoted from the bench into the unfamilar role of five-eighth.
Lyons spot on the bench has been filled by 18th man Addison Demetriou, who will make his Holden Cup debut.
A Canterbury Bulldogs junior and former NSW Under 16s representative, Demetriou trialled with the young Roosters at the beginning of the 2014 season before putting in a string of impressive performances for Kingsgrove Colts to earn a call-up for today's clash with the Wests Tigers.
A backrower by trade, Demetriou has "earnt" his debut in the eyes of Coach Hartigan.
"He's earnt his spot in the side with impressive showings so far this season," Hartigan said.
"We're excited to welcome him into the side for tonight's match and are sure he'll fit in well."
In another change to the side named on Tuesday by Hartigan, Jokatama Dokonivalu will start from the bench with Jake Lewis set to start in the front-row in jersey number seventeen.
Dokonivalu is set to make his first appearance since being carried from the field with a knee injury in Round 4.
Mitchell Subotin comes into the side as 18th man.
Roosters (1-13): Nene Macdonald, Arthur Currie, Brendan Elliot, Taane Milne, Jack Goodsell, Alex Lyons, Tyler Cornish, Braden Uele, Alex Thomas, Jake Lewis, Vincent Leuluai, Willis Meehan, Piki Rogers
Bench (14-18): Harry Vanderhart, Mitch Mamary, Jokatama Dokonivalu, Addison Demetriou
Gates Open for tonight's clash with the Wests Tiger at 5pm, with the Holden Cup clash kicking off at 5.15pm before the NRL fixture at 7.40pm.
