North at center of another concussion controversy in rugby
NORTHAMPTON, England — Wales winger George North is at the center of another concussion controversy in rugby that is highlighting the limitations of the technology available to doctors to assess head injuries.
North, who has suffered a series of concussions over the past two years, was cleared by doctors to continue playing in a match for Northampton against Leicester in the English league on Saturday, despite replays suggesting he had been knocked out following a tackle.
