Cape Town - Griquas lock Jonathan Adendorf is "lucky to be alive" after he was stabbed four times in Kimberley on Saturday night.Griquas president, Arni van Rooyen, told the Volksblad website the lock is currently recovering in hospital after he was first robbed and then stabbed with a knife outside a Kimberley nightclub.The incident happened mere hours after Adendorf played for Griquas in their 20-19 Currie Cup loss to Western Province.Adendorf and Griquas' physiotherapist, Lance Lemmetjies, reportedly left the Kim by Night club with their partners on Saturday night when Adendorf was attacked while on his way to his car."Of what we understand, Lance stopped to talk to someone outside the club while Jonathan walked on to his car."On his way someone apparently hit him over the head with a hard object and searched his pockets while he was lying half-conscious on the ground."Then he was stabbed four times with a knife. His lung was perforated by one of the attempts. He is lucky to be alive."It's a massive shock to all of us. You don't expect this to happen in Kimberley," said Van Rooyen.Adendorf's absence will be a big blow to Griquas' Currie Cup hopes."From a rugby point of view, this is a massive blow for us. The possibility exists that Jaco Neggen (lock) could miss the next couple of weeks and Jonathan is also sidelined for at least six weeks," said Van Rooyen.Griquas tackle the Free State Cheetahs in Bloemfontein on Saturday (15:00 kick-off).
