 Wilkin has established himself as one of the sport's brightest young talents |
St Helens trio Jon Wilkin, James Graham and Ade Gardner have all committed their futures to the club after signing new long-term contract extensions. Wilkin, 23, has agreed a five-year deal, while Graham, 21, and Gardner, 23, have signed for another four years.
"All three are integral as we bid to retain our titles this year and we're delighted to secure their services," said Saints chairman Eamonn McManus.
Sean Long, Keiron Cunningham and Maurie Fa'asavalu all signed new deals in May.
Wilkin, Graham and Gardner - who all played for Great Britain against France last week - played key roles in Saints' superb 2006 treble-winning season.
The news of the trio's contracts follows St Helens submitting an application to build a new 18,000 capacity stadium to replace Knowsley Road.
"It has certainly been a busy week for us," added McManus.
