Simon Stead admits he’s behind schedule with his recovery from serious arm and leg injuries.
The Tigers’ skipper has been out since April after a horror crash at Rye House and has missed out on a late season return.
And he still can’t say for certain whether he will be back on a bike before Christmas to establish his chances of racing in 2016.
He said: “It’s obviously taking a little bit longer than I would have liked - I knew it was going to be a bit of a long, slow process from the beginning but we’re seeing steady improvement and that’s all I can really hope for at this stage.
“The hospitals and the surgeons are happy with the progress that we’ve had so far, we’re continuing to work hard on my fitness with the training to build the muscle back in my arm and leg.
“I’m back training with (former championship boxer) Ryan Rhodes who helped me through the last lot of recovery I did a couple of years ago.
“We’ve got a big challenge on this year but again, Ryan will be instrumental on helping me back to full fitness.”
Meanwhile Jason Garrity is facing a race against time to be ready for Sheffield’s play-off visit to Peterborough on Sunday with bad swelling on the foot.
He’s set to make a decision on Friday as to whether to try and race or to allow Tigers to book a guest.
Tigers co-promoter Damien Bates said: “We are taking it day-by-day with Jason because the swelling on the foot is bad right now and they can’t establish the full extent of the damage. He’s been magnificent for us this season and we desperately need him but right now his chances are no better than 50/50.”
Garrity missed Coventry’s Elite League play-off clash at Poole on Monday which saw the Pirates reach the Grand Final. They will face Belle Vue over two legs next week with the first leg on Monday.
