Former captain Jeff Wong Chun-kiu gets one shot at winning back his place in the Hong Kong squad for the Asian Games at the Singapore Cricket Club Sevens this weekend. Wong has been racing against time to get fit after surgery on a debilitating knee injury, which has kept him out of action for almost a year. 'I had surgery in April and the knee has been coming along okay. But this tournament will be a good test for me and for my knee, and I hope I can prove myself,' the 25-year-old Kowloon scrumhalf said. Head coach Dai Rees is a big fan of Wong, but said time was running out for the livewire scrumhalf, especially with intense competition for places. 'Yes, it is make or break for Jeff. This is his first tournament in a year and we will have to see how he goes. He has had a couple of training sessions, but it is not long enough,' Rees said. Wong hurt his anterior cruciate ligament in his left knee last October as captain of the Hong Kong team at the Asian Sevens Series tournament in Kota Kinabalu. He continued playing until December's East Asian Games when the injury inflamed, forcing him out of contention on the second day of the competition. Picked to lead the national side for the first time at the Hong Kong Sevens in March, Wong had to pull out after his left knee inflamed again. 'I haven't played a competitive game of sevens since the East Asian Games. I have had a couple of games of club rugby these past few weeks and I have been training with the sevens squad,' he said. 'But this weekend will be the first big test for me. I won't say the pressure is on me but I will have to see if I'm up to speed. 'The team has been doing well and there is a lot of competition.' Wong's main danger for the scrumhalf berth will come from Hong Kong Football Club's Jamie Hood, who has been in impressive form and played a significant role in Hong Kong winning the Cup competition at the Borneo Sevens last Sunday when they defeated Japan 31-28. 'Jamie has been playing well and we will have to make a couple of tough decisions, not only for the scrumhalf position but right through the team,' Rees said. 'We have 17 players who are all in contention for what will be a strong Asian Games team and, as a coach, it is a nice position to be in.' Hood and Adam Raby will not be playing in Singapore as Rees tries out other players. But the presence of Mark Wright and Rowan Varty will boost Hong Kong's chances in Singapore. The duo had been expected to return for club duty with Toyota Shokki Shuttle but have been granted permission to stay on. Rees will name his 12-strong Asian Games squad on Monday.
