Rantie has not appeared in Durban for Bafana training this week, having had his traditional wedding last weekend. His white wedding is said to be on the same day as the Bafana match.
Gabuza, 27, has spent long spells on the sidelines at the Buccaneers, but has been in fine form for them of late in the Caf Confederation Cup.
The former Golden Arrows striker, who signed for Pirates in 2013, scored three goals in two games to help the Buccaneers beat AS Kaloum and qualify for the Confederation Cup group stages.
Gabuza has played for Bafana before, making his debut when they beat Mozambique 2-0 in a friendly under Gordon Igesund on September 11, 2012.
Current Bafana coach Shakes Mashaba could now even hand Gabuza a surprise start against the Gambia, as he is rather short on natural strikers in his squad.
Thamsanqa Gabuza will replace Tokelo Rantie in the Bafana Bafana squad. #Phakaaathi
