Tim Sheens says Hull KR are not scouring the transfer market at the moment, despite several first-team players being on the treatment table.
The Rovers fell short to a 36-24 defeat to league leaders St Helens at the Totally Wicked Stadium on Friday night.
And with first-team regulars Danny McGuire, Robbie Mulhern, Adam Quinlan, James Greenwood, Lee Jewitt, Ryan Lannon, Will Dagger and Nick Scruton all sidelined, Sheens admitted injuries are taking their toll on his side.
Speaking after their loss at Saints, Sheens revealed: “The big issue is, is that we are still a little underdone in terms of grunt in the middle.
“We got [Mitch] Garbutt back tonight and you could see the difference he made when he came on but we need a couple of our starting props back to help with our rotation.
“I’m desperate for guys like Robbie Mulhern and Lee Jewitt to come back into the side.
“Our situation at the moment as a club is that we are having to deal with it until we get to the point where we have injured players coming back. Losing Greenwood for the year has been a big blow for us but from a point of view of buying or loaning anyone, we aren’t doing anything like that at this stage.”
Hull KR currently sit in eighth in the Super League table after winning just three out of their first nine games of the season.
And Sheens believes there is still some way to go until they see the light at the end of the tunnel when it comes to getting injured players back.
He added: “At some stage we will have Adam Quinlan and some of our better players on the field and hopefully we’ll have something like our best side available and I’m hoping that day will come sooner rather than later.
“People will say ‘you should still be winning’ but we aren’t a club with the depth of a Warrington or St Helens in terms of the numbers we’ve got.
“We need to have close to our best side to be competitive and a number of sides are like that. You can only go so far with lads who aren’t experienced enough and we have some new combinations too.
“We’ve got to try and stay strong. We have got to really knuckle down in the next couple of weeks and put a win on the board.”
Sheens confirmed that veteran Danny McGuire and front-rower Robbie Mulhern will return for Thursday’s home game against Leeds Rhinos.
