Wakefield have been dealt a double injury blow with news on forward Jay Pitts and Max Jowitt.
Pitts, 32, has been ruled out for the rest of the season after having surgery on his hand, while Jowitt will be out for a few weeks with a hamstring injury.
Trinity’s head physio, David Cooper, said: “Jay has suffered a fracture to his hand which was operated on in order to stabilise the bone and allow healing. The recovery time for this will take him until the end of the season.
“Max picked up a hamstring strain on Sunday at Hull KR. The initial signs are that he will be out for a number of weeks. However, the club and Max will be doing everything to ensure that his time on the sidelines is as brief as possible and to have him back in good condition to still play a big part in the rest of the season.”
Pitts had been an ever present for Wakefield this season, making 21 appearances.
Full-back Max Jowitt has scored five tries in 14 appearances, but sustained an injury in the 15-10 defeat to Hull KR at the weekend.
That defeat has seen Wakefield slip to the bottom of the Super League table, below Toulouse.
Trinity host champions St Helens on Sunday, before a local derby with Castleford on Friday week.
In August they have three home games against Catalan, Wigan and Hull KR, with trips to Hull and St Helens in amongst them.
Their final game of the season is away at Huddersfield on September 3.
Wakefield have lost their last four matches, since back-to-back victories over Hull and Warrington at the start of June.
They have won five games in total in the league in 2022 – the other three all coming back to back in March/April, against Toulouse, Warrington and Salford.
