According to reports in the French press, Springbok lock Juandre Kruger has signed with Top 14 club Racing Métro.
On Thursday, Parisian radio station RMC announced that Kruger, who has eight Test caps for South Africa, is the latest high-profile addition to the big-spending French club's squad after the recent acquisition of Wales centre Jamie Roberts.
Kruger was named the Bulls' Super Rugby forward of the Year for 2012.
If the reports are true, it will not be the lock's first stint in Europe after spending two years with Northampton Saints in England.
Rumours are circulating that Racing have also signed Northampton front-row duo Soane Tonga'uiha and Brian Mujati, Perpignan wing Adrien Planté, and Welsh international flank Dan Lydiate.
