STEVE Burton will make a last-ditch bid to prove his fitness for the territory's Hongkong Sevens squad. Burton, Hongkong's skipper at last year's Asian Championship, was two weeks ago selected for a 10-man squad to compete in the Hongkong Sevens from March 27-28. But a serious illness, which put him in hospital for several days, forced the Tigers number eight to miss last week's Canberra Sevens and almost certainly rules him out of the Hongkong event. Club full-back Justin Weston has been drafted in, but Burton said he will train on Monday. ''I'm still recovering,'' said Burton, who suffered from a blood infection. ''At the moment I'm a bit off-balance because of an infection to my ear. Apart from that I feel fine. I've lost a stone, so I don't know how I'll react on Monday. ''But I'll give it one last go. I'm still hoping for the Hongkong Sevens. But if that doesn't happen then I will aim for the World Cup.'' Burton was unable to attend last night's training session at Aberdeen Sports Ground and will also miss tomorrow's workout at Happy Valley. National coach George Simpkin, must decide on Monday whether to keep Burton in his 10. Simpkin will choose another 10-man side for the World Cup sevens, from April 16-18, at Murrayfield, Scotland. Burton made his sevens debut for Hongkong at last year's Sicily Sevens, when the territory qualified for the World Cup. Meanwhile, giant lock Tony Ridnell, who was originally left out of the squad, will take part in the Sevens after all, following the withdrawal of injured Tom Brewer who damaged knee ligaments at last week's Canberra Sevens. The Welsh President's squad will field seven internationals at this month's Hongkong Sevens. Among them are captain Rupert Moon, Scott Gibbs, Nigel Walker, Emyr Lewis and Mark Perego, who will all be on duty for Wales against France in their Five Nations Championship finale in Paris tomorrow . The other two internationals in the 10-man party are Wayne Proctor and Aled Williams, who was part of the Welsh team that reached the semi-finals of the 1990 Hongkong Sevens. Welsh President's squad for Sevens: Rupert Moon (Llanelli, captain), Robert Howley (Bridgend), Aled Williams (Swansea), Scott Gibbs (Swansea), Nigel Walker (Cardiff), Wayne Proctor (Llanelli); Emyr Lewis (Llanelli), Mark Perego (Llanelli), Andrew Williams (Maesteg), M. Thomas (Rosslyn Park).
