Masuku's response to being replaced at half-time was by placing a head-set, deemed disrespectable by Orlando Pirates' fans.
The act will ask fresh questions about new coach Vladimir Vermezovic's control over the dressing room, at a time during reports of concern toward the Serbian's methods from his time at Kaizer Chiefs. Vermezovic's reported outbursts at AmaKhosi spread amongst PSL players, so Masuku will be 'listening to the music' for his behaviour.
This is an incident which Masuku alone has to answer to, no matter the reasons for his replacement at the break. The winger has responded by apologising with the following statement through the Pirates official website:
"I wish to apologise unreservedly to the chairman of the club Dr Irvin Khoza, the management, the technical team, my teammates, the League, the club fans and the sporting fraternity at large, for acting in the manner I did in the match against Santos, while sitting on the bench.
"After being substituted, I was overcome by emotions thus I acted in the manner I did, which I understand is by no means justifiable," wrote Masuku.
"I have been in football for a few good years, and I could have handled my personal frustrations a lot better.
"I know that wearing headsets/headphones while on the bench is unacceptable and above all disrespectful and it is for this reason that I have written this apology letter.
"Once again I want to express my deepest regret at what I did.
"Thank you," the statement ended.
