United Rugby Championship (URC) organisers on Tuesday confirmed that the Round 6 fixtures that were postponed in October will take place at the end of February.
The Sharks v Ulster and Lions v Glasgow Warriors fixtures were postponed due to severe gastroenteritis outbreaks in the travelling team's squads.
The rearranged games will take place on Saturday, 25 February. The Sharks will host Ulster in Durban at 14:00, before the Lions welcome Glasgow in Johannesburg at 16:10.
"The league would also like to thank all teams and broadcasters involved for their patience and understanding in this situation," A URC statement read.
These matches will take place the same weekend as round three of the Six Nations which means Ulster and Glasgow will be without their national players.
