After watching them against Hunslet yesterday, I don't think we've too much to worry about. Regarding Aaron Smith, I've seen him play for Bradford and Cas mainly as a back up to more senior players at those clubs but he should do a good job for us. Think I've seen him play hooker, but don't quote me on it.
Looks like some of the players that played at Wakefield may get rested, with the ones that have now served their bans coming back in along with the young players.
