Springbok front-row duo Bismarck and Jannie du Plessis are reportedly set to mull over possible moves to the Top 14 at the end of the current season.
According to Eyewitness News Sport, the Sharks pair are set to talk to a French agent this week about "a number of offers made to them".
"My contract finishes with the Sharks at the end of this season, there are some people coming to have a chat with us about clubs," said Bismarck.
"We are seeing somebody Thursday."
Bismarck added: "There are a few clubs that are interested but I'm very happy at the Sharks. I've first got to first speak to the Sharks as it's home for me, and I love the Sharks."
The South African publication believe that Top 14 giants Toulouse are the favourites to capture the Du Plessis brothers, with fellow Springboks Gurthrö Steenkamp and Gary Botha at the club.
