Wakefield coach Chris Chester fears veteran half-back Danny Brough suffered an anterior cruciate ligament injury against Hull KR on Friday night.
Brough, 37, picked up the injury in the first half and tried to run it off, but could face sitting on the sidelines for the entire season if Chester’s worst fears are realised.
He said: “We have just got to get on with it. We can’t feel sorry for ourselves.
“It’s not great for Broughy but it certainly looks like an ACL. I’m really disappointed for Broughy who has been great in pre-season and was looking in great shape.”
Trinity were soundly beaten 30-12 by relegation favourites Hull KR at KCOM Craven Park, with winger Ben Crooks scoring four tries.
Chester added: “(I was) very disappointed in the effort of some individuals tonight. I thought we just got outmuscled.
“I was disappointed with the errors, 16 errors, you can’t win any games playing like that.
“Guys were just probably trying too hard, guys just making stuff up.
“It looked like we were a group of players just thrown together. We need to be a lot better so I expect a big reaction next week.”
