Manly back-rower Jack Gosiewski.

With Manly's season hanging by a thread after a 26-12 loss to the Cowboys at Lottoland, Sea Eagles coach Trent Barrett can't even consider resting Jake and Tom Trbojevic after Origin I.

Compounding the loss to the Cowboys were injuries to Jack Gosiewski, who suffered a broken arm, and concussions for Jorge Taufua and Shaun Lane.

Dylan Walker and Taniela Paseka are still two weeks away from returning so Barrett is desperate for the Trbojevic boys to come out of Origin unscathed and take their place against the Warriors in Christchurch next Saturday.

"Yeah, they (Jake and Tom) are coming, they will leave straight from Melbourne to come," Barrett said.

"If they don't play we probably won't be able to fill the team.

"We'll have to see how the two boys go with the concussion and we will miss Gosiewski, so they are definitely coming.

"Walker is still a fortnight away, Paseka is still a probably a fortnight away, so it will just be a bit touch and go coming into the back end of next week and hopefully the two boys get through the Origin."

In his first match back from six weeks out with a broken hand, Gosiewski was placed on report for a late hit on Johnathan Thurston and could be sidelined for a month with a broken arm.

Lane hit the ground hard with five minutes to go and was lying motionless before starting to convulse. He managed to walk off the field but failed a HIA test and was sent hospital for further evaluation. Taufua didn't return in the second half after failing an HIA test.

"Gosiewski has got a broken arm, he's gone to the hospital," Barrett said. "Lane is up and about but he's not great, we'll have to watch him. Taufua is up and around but the same."

After strong wins over Brisbane and Melbourne gave hope of a revival, the Sea Eagles have slumped to back-to-back losses to Canberra and the Cowboys and Barrett said a few players will not be looking forward to Monday's video session.

"All I want every week is effort and consistency, regardless of who you throw out there and regardless of the result at the end," Barrett said.

"There's going to be some players that are a little bit embarrassed in video on Monday with some of the thing that happened throughout that game.

"It's a part of learning but it's a tough competition and if you don't aim up every week you get beaten."
