Craig Whyte, who took over the club in May, was the subject of a BBC Scotland documentary on Thursday night which alleged that the businessman continued to run a former company, despite being banned from doing so.
However, McCoist is adamant that his players will not be thinking of the allegations when they take to the field at Tynecastle this weekend.
"My players are really focused and everybody should know that," he said.
"Over the last four or five years there have been ups and downs as there are at any club.
"Our players to a man have remained wonderfully focused and they are still focused."
When questioned about Whyte, McCoist was in full support of his fellow Scot.
"He's been great, absolutely smashing," he added. "I spoke to the owner this morning as I always do and we had a good chat.
"I will not comment on any televivision programmes."
The Gers are currently seven points clear of second-placed Motherwell in the SPL table.
