Clarke, who was forced to make a change to his line-up as Gary Liddle started with Danny Guthrie missing out through injury, admitted he was a little surprised as James Clarke's error led to the game's opening goal.
The gaffer, who has managed Clarke at both Salisbury City and Bristol Rovers, insisted that such errors are collectors items and are somewhat unheard of as James is among the more consistent players in the group.
The Saddlers were able to remain calm and, after prodding and probing their opponents, were rewarded with a goal four minutes from time as James Hardy came of the bench to score his first goal in what was his EFL debut.
Speaking to the assembled media, Darrell went on to praise his team for their mental strength as they avoided defeat in front of over 5,000 fans at a atmosphere-filled Banks's Stadium.
The manager, pictured during last weekend's victory over Northampton Town said; "I thought we started well and then we conceded a sloppy goal which is unheard of really from James Clarke, the amount of years that I have managed him.
"I asked the boys for a response and throughout the course of the season, when your team-mate makes a mistake like that, it’s about getting him out of the verbal. We certainly kept going, changed things around, asked a few questions of them. It was an okay performance.
"I think at times there could have been better decision-making, certainly in the final third. I thought we got a deserved equaliser. And that’s what I say about mental strength in my teams, making sure that we never know when we are beat.
"The fans can feed off that sort of energy levels. Yeah, there can be one or two moans and groans if we don’t make the right decisions with the ball, when we can go forward and we don’t need to go back, but when they see that they will get behind the lads and I thought we kept going and got a deserved equaliser."
