The Saddlers, who have lost seven of their last eight league outings, play host to the Posh at Banks's Stadium clear in the knowledge that anything less than a win will see them relegated to the fourth tier of the English game for the first time in a decade.
The 24-year-old, who is likely to line up alongside top scorer Andy Cook as interim boss Martin O'Connor looks to earn the first win of his current spell at the helm, admits the Saddlers are lucky to be still be in with a chance of securing survival and has urged his teammates to make the most of it.
Josh, who was speaking via the Express & Star, said; "We have gone seven games without a win and we are still in it – that is the crazy thing about it. Peterborough is going to be a tough game, they are fighting to get in the Play-Offs.
"But we have got to put in a performance and show a bit of dignity. We are four points from safety. Teams have still got to play big teams. Teams have still got to play teams around them.
"It’s not over yet. We’ve been given so many chances to get out of it – in these two games we have just got to give our all. I know that’s been said before and it’s not happened. But the only thing we can do is go into Saturday and get a result and then go to Shrewsbury on the final day and get a result there."
