St George Illawarra coach Paul McGregor has amended his squad to 19 ahead of the Dragons' Round 4 clash against the Newcastle Knights at McDonald Jones Stadium on Sunday, April 7.

Luciano Leilua and Jonus Pearson are the two players to drop out of the initial squad named on Tuesday.

Tyson Frizell has been promoted from the reserves into the 17 as a result of Leilua's omission; a positive sign the New South Wales and Australian representative will play his first game since Round 1 after suffering a lacerated testicle.
