Graham Henry has given Wales a massive boost by pledging to complete his lucrative five-year contract as coach.

With the Principality reeling from a player eligibility scandal and the sudden resignation of conditioning coach Steve Black, Henry's vow could not have been better timed.

"I will be here until 2003," he said last night, scotching speculation he was considering an early return home to New Zealand.

"I have thought about things quite deeply over the last few weeks, and thought to myself, `It's a pretty interesting situation you've got yourself into here, mate'.

"But it has all made me more determined to do the job as well as I can."

While Wales and Henry got back on the winning track with Saturday's victory over Scotland, Welsh Rugby Union (WRU) officials were putting finishing touches to a sweeping review of all their top players' qualification credentials.

WRU secretary Dennis Gethin ordered the investigation following newspaper allegations that neither New Zealand-born Welsh internationals Brett Sinkinson nor Shane Howarth were qualified to represent their adopted country.

Neath flanker Sinkinson and Newport full back Howarth, who have won 33 caps between them, each claimed a Welsh grandparent connection, but there is now grave doubt about both players' backgrounds.

WRU findings will be forwarded to the International Rugby Board (IRB) today, who will decide on any sanctions such as fines or possible deduction of Six Nations points.

But Gethin last night insisted: "At the time the two players were selected, we were convinced they were eligible to play for Wales. I have letters, etc, which on the face of it, were evidence that they were qualified.

"Whether that satisfies the IRB remains to be seen. I still live in hope that they (Sinkinson and Howarth) might be back in the fold at some future date.

"The rules are crystal clear, but they don't say what documentary evidence is required. Whether our procedures were rigorous enough at the time is something we need look at," he added.

"The IRB will discuss our report and let us know their decision in due course, but my personal hope is that a line will be drawn under it, and in future, we will all know where we stand."

Meanwhile, Cardiff and Wales lock Craig Quinnell's season could be over, if fears about a back injury are confirmed. Quinnell has not played since the England defeat.
