Concussion worry won’t prevent George North playing on

George North has vowed not to let a series of concussions and the controversy around them drive him out of rugby.

The Wales winger was knocked out for the fifth time in Northampton’s Aviva Premiership loss to Leicester on December 3. There was a storm of criticism on Wednesday when the Saints were cleared of any wrongdoing after allowing North to return to the game.

Meanwhile, former World Rugby medical adviser Barry O’Driscoll was one expert to suggest North, just 24, could retire from the game for the sake of his long-term health. But the rampaging back will not entertain any such notion, insisting he will instead follow the example of Wales’ veteran front-row warrior Gethin Jenkins.
