Right-back Facey made way for injury returnee left-back Cameron Pring as the manager sought to relocate James Clarke to right-back as the club captain had endured a poor opening forty-five minutes.
Despite being known for his versatility, 30-year-old Clarke, who had entered a superb performance at left-back during the recent away over Port Vale. struggled throughout the clash with Macclesfield, regularly giving the ball away.
Speaking to the assembled media following Saturday's draw with the Silkmen, Darrell said; "I probably made a bad call at half-time to be honest. Clarkey, who has been very, very reliable this season was poor.
"I just thought we were a little bit short at set pieces, so I hold my hands up for that decision. It was a tactical change that didn’t work. Honest as the day for me.
"I looked at it and thought that if I take Clarkey off then we’re very short at set pieces at that present time and a second goal kills the game. As it happens, Clarkey’s had a nightmare with the ball. I take it on the chin."
