St George Illawarra firebrand James Graham is bullish about his side covering the loss of Tyson Frizell as they prepare to meet a red-hot South Sydney on Thursday night in the NRL.

The Dragons could be without their enforcer for up to six rounds after he underwent testicle surgery after copping an accidental low blow in Saturday’s 24-12 loss to North Queensland.

Graham said they had no excuses as they sought to rebound against a Rabbitohs side fresh off a win against incumbent premiers Sydney Roosters.
