Warlingham travel to Weybridge Vandals this Saturday eager to build on their lead in London South-West 4, but with a major injury doubt over Neil Robson, the Hamsey Green club's talismanic back-row forward.

Robson suffered a hamstring pull late on in Warlingham's 63-0 yomp over Farnham two weeks ago, a game in which the No8 scored four tries.

"I pulled my hamstring late on, calling a mark in our 22," Robson said. "I was a bit tired, clearly a forward's not meant to run all those yards in a game."

Robson has been undergoing treatment on his hamstring under the supervision of Lacey Congram, the England international lacrosse player who works as Warlingham's physiotherapist.

"Neil's important to us, an experienced head among our young side, so obviously we're keen to have him back for the run-in to the season," Tony Doe, Warlingham's playing chairman, said.

Apart from Robson, Warlingham coach Neil Crammond hopes to have a full squad to select from for the visit to Weybridge, who are fifth in the division and have a strong home record this season, including a recent win over promotion challengers Wellingtonians.

"Every game is a must-win for us now," Doe said, "we cannot afford any slip ups."

At 27 years old in a side with an average age of 22, Robson is aware that he is one of Warlingham's senior players, and he has been relishing the the responsibility.

Robson has been playing in Warlingham's first XV for a decade, and he recognises that the demands of the sport at this level have increased considerably. "Teams now are stronger, more physical and a lot fitter," he said.

He fits his training in with his work as a financial adviser. "We have tough training sessions at Hamsey Green every Tuesday and Thursday, but I also train on my own three times a week, and that's what most of our squad is having to do."

Warlingham's other teams are showing similar winning form to the first XV, the 2nds beating Croydon 29-5, with Alan Andrews the Man of the Match, and the 3rds winning at Old Walcountians 29-8.
