Chase has only been back in training for a few days. May need a bit of time to reach match fitness or just has to earn his place in the side due to the fine form of Ben Reynolds.
Tonga has a bad knee, frustrating but I guess it can't be helped and needs a bit more time.
Unless you meant Beswick? Not sure what is happening with him. All noise of him going to Wigan has gone quiet but I haven't heard him mentioned in terms of a return date or even an injury update in a while. Although he is still turning up on match days to support the lads so I assume he will be back eventually.
Strong looking team and nice to have a few options in the back line again. Worthington was in good form before his injury so will be a tough choice between Worthington/Armstrong/Whiting in the centres.
