St George Illawarra coach Paul McGregor has named his mandatory 21-man squad ahead of the Dragons' Round 5 clash against the Canterbury-Bankstown Bulldogs at Netstrata Jubilee Stadium, Kogarah on Sunday, April 14.

Korbin Sims's broken arm has caused a reshuffle to the Dragons' forward pack, with Jacob Host named on the interchange in Sims's place.

Tyson Frizell will start in the back row and join James Graham and Cameron McInnes as co-captains of the team.

The Dragons will look to make it three wins on the trot following their thrilling golden point victory over the Newcastle Knights in Round 4, against a Bulldogs team who took the undefeated Melbourne Storm to their limit last weekend.

The Dragons Canterbury Cup NSW side will act as a curtain-raiser to this game, and will kick-off at 1:50pm.
