The sentence handed down was three years with one year suspended, implying an effective two years direct jail term.
In April this year, Lungisa was found guilty of assault with the intent to cause grievous bodily harm in the Port Elizabeth Magistrate’s Court.
Magistrate Morne Cannon said he proved to be a poor witness who changed his version of events as the trial proceeded.
Lungisa was found to have unlawfully and intentionally hit Kayser over the head with a glass water jug without provocation.
His co-accused Gamalihleli Maqula was acquitted on all charges in March when the court found that there was not enough evidence against him for conviction.
Speaking after Lungisa's sentencing, Kayser said he believed justice had been served.
“I am convinced that we have an independent judiciary.
“The outcome has proven that I was correct to put my trust in the judiciary and that justice has been served.”
