Knights forward, East Maitland junior and former Kurri Kurri Bulldogs first grader Robbie Rochow will make his Knights debut tomorrow at Hunter Stadium after Wayne Bennett ruled out Neville Costigan from the Round 19 encounter.
Despite training today, Costigan is forced out due to a bicep injury.
Rochow will start the match on the bench.
Rochow returned to the Hunter Valley, following a stint with the Melbourne Storm, to sign a one-year contract with the Knights for 2012.
After a 2011 season hampered by injury, Rochow has worked hard in 2012 to earn a spot in the Newcastle Knights first grade team.
The Knights take on reigning premiers the Manly Sea Eagles at Hunter Stadium.
Kick off at 5.30pm.
