Northampton Saints wing George North over concussion
George North says the problems he had with concussion earlier in 2015 are firmly in the past and he is focusing on success with club and country.
The Northampton Saints wing missed five months after suffering four blows to the head over a short period of time, with some suggesting his career could be under threat.
However, he returned to action ahead of the Rugby World Cup as Wales took on Ireland, and went on to play four matches as they reached the quarter-finals.
North has since made three appearances for Northampton in the Premiership, but he is still waiting for his first try of the 2015-16 season.
"From my point of view that's behind me now [his concussion problems], I'm over it," he told BBC Radio Northampton.
"Initially it was a bit worrying, everyone saying that's my career finished. My first game was Ireland away for Wales - as soon as the whistle went I was happy to be back.
"I'm feeling pretty good now. It's just nice to be back playing and not to be worrying about my head too much."
