In October 2013 he began training with Mpumalanga Black Aces. Despite rumours linking him to former club Orlando Pirates, Mabizela signed a deal with Black Aces till the end of the 2013–14 season. In June 2014, the Black Aces spokesman Gordon Masondo confirmed that Mbulelo Mabizela's contract had been renewed until 30 June 2016. However, he was frozen out of the squad in October after falling out with manager Clive Barker, including a bust-up with a veteran coach and was released in December based on the recommendations of a disciplinary enquiry following his misbehavior.
