With the unavailability of Paul Gallen and Anthony Tupou two more young players, both local juniors, will debut for the Sharks today.
Sione Masima, from the Gymea club and Scott Sorensen, a Cronulla-Caringbah junior, have been included in the Sharks team with both to play off the interchange bench.
The pair are backrowers, with Sorensen, the cousin of former Sharks stars Kurt and Dane Sorensen, also capable of playing hooker.
Tupou Sopoaga and Blake Ayshford move from the interchange bench and will start the match in place of Gallen and Tupou.
Kickoff to the NRL clash is at 2.00pm
