The controversial owner vowed to stay away from matches at Field Mill last September, amid further protests from fans calling on him to sell the club.
Mr Haslam, who has since ended his day-to-day involvement in the running of the club by appointing chief executive Stephen Booth in December, said at the time: "All of this has been deflecting away from the team and that is not good. The abuse doesn't affect me, but it is not in the interests of the club."
His decision to stay away has not stopped fans chanting for him to quit the club during matches and staging protests outside the ground - and many thought that he would attend the Boro match because of its high profile.
But this week when asked by Chad if he would be going to the Fourth Round cup tie, which is being screened live on BBC 1, he said: "I have not really thought of going . . . I have no intention of going at this moment in time."
Mr Haslam said that he would be following the game on Match Of The Day and also expected to spend Friday evening in Sheffield with some of the BBC's football presenting team - including Gabby Yorath, Lee Dixon and Carlton Palmer - who will be at Field Mill for the potential giantkilling.
He added: "The cup tie is good for the fans, the players, everyone connected with the club and the town.
"This is what the cup is all about. I am sure it will be an exciting game with the potential for an upset; we need a good crowd to get behind us.
"For the players it is a chance to put themselves in a good light on national TV and a welcome relief from the relegation fight.
"Really, only positives can come out of it."
Mr Haslam was at Brighton to watch the Stags spring a surprise in the Third Round and added: "We fully deserved that result. All the people at Brighton were very complimentary and positive about us, saying they could not understand why we are in the position we are in the League.
"We have now had two good away wins and were, I am told, unlucky on Saturday against Darlington. We have the ability to do well."
