JONNY WILKINSON could miss England’s Six Nations campaign after being ruled out for up to FIVE MONTHS.

The World Cup hero dislocated his knee on Tuesday — his 16th injury since leading England to glory in 2003.

He damaged ligaments and cartilage. A pal said: “Jonny knew as soon as it happened that it was serious because of the pain — and he was kicking the turf with his other leg in agony.

“He was really down about it in the dressing room afterwards but is determined to fight his way back.

“He has been hit with so many injuries in the last five years that anyone else would just throw in the towel.

“But he has been incredibly positive about the injury and is determined he won’t be beaten by it.”

Newcastle’s jinxed fly-half is now set to go under the knife by the end of the week, ruling him out of England’s autumn Tests. And he will almost certainly miss February’s Six Nations campaign as well.

Tuesday’s clash with Gloucester was only Wilko’s third game since returning from a six-month lay-off after shoulder surgery.

Wilko seemed to have put his injury misery behind him after leading England to last year’s World Cup final.

Yet the Falcons ace, 29, has been crocked an amazing 16 times since lifting the World Cup in 2003 — including kidney, bicep, thigh and neck problems which have threatened to ruin his career.
