Raiders coach Ricky Stuart has left the door open for a shock Sia Soliola return against St George Illawarra in Wollongong on Saturday, while enforcer Josh Papalii will be given all week to prove he's recovered from a shoulder injury. Soliola hasn't played since suffering what looked to be a season-ending facial fracture in early July the last time Canberra played the Dragons, but is expected to engage in full-contact training during the team's main session on Wednesday. His inclusion could hinge on the fitness of Papalii, who was cleared of serious shoulder damage after leaving the field early in Saturday's loss to the Sydney Roosters. Should Papalii fail to recover in time for this weekend, Soliola could potentially take his spot although Stuart is cautious about rushing the veteran front rower back into the fold. Rookie winger Semi Valemei has been named in the starting side once more with Curtis Scott due to miss another week with the leg injury he suffered in the win over Canterbury two rounds ago.
