Wiedwald returned to the starting line up for the win at Barnsley last month, having been dropped for the previous seven games.
The German made a number of howlers before head coach Thomas Christiansen gave Andy Lonergan a go between the sticks.
But Lonergan also failed to cover himself in glory, which prompted Christiansen to restore Wiedwald.
And former Leeds midfielder David Prutton believes a new keeper should be considered in the January transfer window if Wiedwald continues to struggle.
“Given that Wiedwald is back in the frame, Christiansen might wish now that he’d backed him and stuck with him through a sticky patch,” he said.
“Alternatively he might find that a break has done Wiedwald good.
“But what’s clear is that Wiedwald needs to produce a big run of performances through December.
“If problems persist then, to my mind, it’s a position Leeds have to address in the January transfer window.
“It was fine for Christiansen to have a look at Lonergan and it’s more than reasonable to give Wiedwald a second chance.
“But the chopping and changing can’t go on indefinitely.”
Wiedwald, 27, was snapped up from Werder Bremen in the summer after Christiansen ditched Rob Green – a decision that still rankles with Prutton.
“I’m going over old ground here but it still surprises me that the club were so ready to replace Rob in the summer,” he told the Yorkshire Evening Post.
“It’s a manager’s prerogative to pick who he likes and I’m all for selecting players in form but to me the decision to give Wiedwald the gloves felt a bit predetermined.
“Christiansen said when he came here that he’d watched a lot of the footage of last season and I’d have thought the evidence would have been pretty favourable for Rob.
“Then again, this is football. They say that managers live and die by their decisions and that was a big one.”
