Ludik was bracketed to play against the Crusaders last weekend but news broke that instead of taking the field he took to the surgeon’s knife.
The Sharks stalwart confirmed on Twitter that the op went well and then confirmed how long he would be out for.
“Out of the theatre. Everything went very well. Just in a bit of pain. You guys don’t understand how much I appreciate all the messages,” Ludik tweeted.
“They say round about 3 months.” He added.
Ludik joins Bismarck du Plessis, Jaques Botes, Willem Alberts, Butch James Jean Deysel and Tim Whitehead on the injured reserve list.
