Kouassi went down in apparent agony holding the front of his shorts and accused MacLean of grabbing him after the pair clashed at a corner during Celtic’s 3-0 Betfred Cup semi-final win.
The Celtic player went off moments later but had been limping prior to the incident.
The incident was missed by officials, but the veteran Hearts striker said: “It was just a laugh, just a coming together. “If I went down every time a centre-half niggled me I would be on my backside all day.
“It was just handbags,” he added.
