Newton has been linked with a move to Bradford

The hooker is now suspended until 15 April, 2006 following the challenges on Lee Gilmour and Sean Long in the Super League clash with St Helens.

That means the 26-year-old will miss 10 league and cup games next season.

Since he has already served one match and a pre-season friendly would count towards the ban, he has effectively had his ban increased by two matches.

Newton had already been ruled out of the Great Britain squad for the Tri-Nations Series with a hip injury that requires rest.

The appeals committee also upheld the �600 fines imposed on the former Leeds player, who has been linked with a close-season move to Bradford.

Newton contested the severity of a three-match ban imposed by the Rugby Football League's disciplinary committee for a high tackle on Gilmour.

He also appealed against both the guilty verdict and severity of a seven-match suspension handed out for a stiff-arm tackle on Long.

Both incidents occurred during Wigan's 38-12 home defeat by St Helens in the penultimate match of the regular Super League season earlier this month.
