Premiership side Sale Sharks are in discussions to sign prop Brian Mujati from French club Racing Metro 92.
The 30-year-old Zimbabwe-born tighthead-prop moved to the Top 14 side from Northampton in 2013.
He began his career at South African club Lions and won 12 international caps for the Springboks.
"He's on the radar. We've met him and we've met several others and we'll see where the negotiations take us," said Sale boss Steve Diamond.
"He's not in the World Cup, so he would come whenever the negotiations are concluded.
"The other two we're talking two would come post World Cup so we'll see which one we get."
Sale made signing a prop a priority this summer and were in discussions with Saracens' James Johnstone, but he opted to join Wasps instead.
