I think it depends on how long he's going to be out.
The longer he's out and the longer Ben continues playing well, then you'd think Jaros might struggle to get back in. I've said before that Ben has a track record of coming back from being dropped and playing better; happened last year with Ross and we could be seeing it again here.
That said, if Jaros is fit for Tuesday and Challinor still sees him as number 1 then I'd put him back in. If Challinor is going to do it anyway, he may as well do it at the earliest possible opportunity.
