article: The Wales and Northampton winger was injured against Leicester on Saturday. TV replays appeared to show him lying motionless before he recovered to pass a mandatory pitch-side assessment. Northampton said they had not had access to full television footage of the incident before allowing North to rejoin the action later in the match. Rules dictate that any player with confirmed or suspected concussion should be permanently removed from a game. Immediately after Saturday's contest, Northampton director of rugby Jim Mallinder said North, 24, had not been knocked out. Premiership Rugby and the RFU have revealed that a Concussion Management Review Group (CMRG) met on Tuesday to assess the incident. A statement said the group could decide to issue a warning or even recommend a misconduct charge against the club or an individual. Wales international North fell heavily in a mid-air tackle that led to Leicester's Adam Thompstone being sin-binned. He left the field for a mandatory head injury assessment by the club's doctor. North was passed fit and returned to the action. After the game, North said on Twitter he was "OK", adding: "I landed on my neck and was worried about it. Thanks to the medics for checking me out properly. I can't help but feel I won't be looking left or right for a few days."

A club statement said that North was "communicating immediately with attending medics" and "complaining of neck pain". It added: "Significant neck injury was excluded on the field but on review of video footage pitch side, the team followed World Rugby protocols and used a Head Injury Assessment given the potential mechanism for head injury. "George was fully assessed by the doctor and passed fit to return to play." But Northampton then released another statement on Tuesday, which said: "It is important to note this video footage is not always the full range of replay angles available to the TV viewing audience at home. "If evidence suggesting a loss of consciousness had been available to the medical team at the time of assessment, George would not have been allowed to return to the field of play." Chris Jones, BBC Radio 5 live rugby union reporter This is turning into a very significant story, with Northampton saying that their medics did not have access to all of the television footage to review North's fall, so rather than withdraw him permanently from the field, they took him off for a head injury assessment, which he subsequently passed.
