The pools are making the long journey to the English Riviera knowing that a win could put them level on points with Torquay – who held a 14-point lead over Challinor side back in december.
But like the Gulls, Hartlepool was recently hit with a mild injury crisis, leading defenders Jamie Sterry and Ryan Johnson have expressed doubts for this weekend’s trip.
But the pair have made the trip and Challinor expects to make a late call to find out if they appear.
“Jamie and Johno are traveling with us, we’ll see how they are and leave it at the last minute,” said the Pools boss.
For us, having one of them be available would give us options, but for them to both be released, we’ll have to look at things. If not both, one will be available to us and allow us to achieve what we want.
“We’re going down and training in Bristol on the way down and making last minute calls on all of them for Tuesday as well.
“We will have to be adaptable and flexible and the team we face on Saturday will be different from the team we face on Tuesday, no matter what.
“That’s what we need to be right now. I’m still convinced that we can put in a positive performance and get a good result.”
The pools will be without club captain Ryan Donaldson (foot) this weekend, as well as Luke Williams, who suffered a “minor setback” in his return to top form.
Claudio Ofosu didn’t make the trip either, but one player is midfielder Tom White whose Blackburn Rovers loan expired on Friday.
Challinor told the Mail: “Tom is with us on the bus so we hope to get him [extension] sorted before the game.
