Sikhakhane passed away from a long illness at the age of 42 last Saturday while on sick leave at Royal Eagles.
His memorial service will be held at the club's offices on the second floor of the Coastland Hotel in Umhlanga on Wednesday from 15h30 until 19h00.
Eagles' game against Mbombela United this Saturday at KwaNyamazane Stadium has been postponed, according to the club.
Sikhakhane, who guided Thanda Royal Zulu to PSL promotion in 2017, was appointed as Eagles coach in February this year, replacing Kosta Papic.
At that time, the club was in dire straits and he managed to save them from relegation.
He also coached Chippa United a few times after serving as an assistant coach when they gained PSL promotion in 2013/14 under Serbian mentor Vladislav Heric.
