Wrestler Jake 'the Snake' Roberts is to undergo surgery to remove a cancerous tumour from his knee.

The veteran Wwe (World Wrestling Entertainment) star has revealed doctors discovered a lump behind his knee, and it is slowly growing into his muscle.

Roberts tells Tmz.com he will undergo surgery to remove the growth on Tuesday (25Feb14), but he is hoping to fully recover in a matter of weeks, so he can get back in the ring for the Jersey Championship Wrestling match on 14 March (14).

He tells the gossip site, "If the devil can't defeat me, cancer doesn't stand a chance in hell! Pray for sick children who face this horrible disease 'cause The Snake will be just fine."

Roberts will be inducted to the Wwe Hall of Fame in New Orleans, Louisiana in April (14).
