CANADIAN John Graf was unconscious for five minutes and had a fit attack as injuries spoiled any hopes the team had of a place in the Cup competition. Graf, one of three Canadian players put out of action, was taken off on a stretcher, and given a precautionary neck-brace, after taking a knock on his head while attempting a tackle on Papua New Guinea's Willie Arthur in Canada's 28-10 Pool B victory. In their second game, the injury-weakened Canadians were swept aside 40-0 by the impressive Welsh President's Seven side, the Welsh sewing up the pool having earlier beaten Papua New Guinea 35-12. Arthur, seconds after Graf's tackle, realised his opponent was in trouble and immediately gestured for help. A medic was on the scene straight away but Graf lay motionless for several minutes before being carried off and taken to the Adventist Hospital. Tournament doctor Mike Fleming said: ''He had a fit after the tackle and was unconscious for five minutes. ''He has made a good recovery but he will be kept in hospital overnight as a precaution.'' Canada, who take on Namibia in the Plate quarter-finals today, also lost Pat Palmer with a hamstring injury and Scott Stewart, who separated his shoulder joint. Glen Ennis, who was part of the victorious Aliens side at this week's International 10s event, was drafted into the side to play the Welsh. But Canada's problems continued with captain Julian Loveday dislocating his shoulder and receiving a cut above his eye while tackling Welshman Aled Williams. Loveday revealed that the injury problems have been an ongoing saga during their Pacific region sevens adventure, which included reaching the final at this month's Canberra Sevens and an indifferent performance at last week's Fiji Sevens. ''We had two guys who had to go off in Canberra as well, so we haven't had much luck with injuries,'' said Loveday. The Welsh, who fielded what is close to a national side, showed a tremendous improvement against Canada and are hoping to shock the seedings when they play Fiji in today's quarter-finals.
