Australian Test hopeful Stuart MacGill's appeal against a two-week ban for disorderly and improper conduct has been dismissed.

As a result the legspinner will miss the chance to press his Ashes claims this week at the Gabba - the venue for the opening Test of the series - when NSW meet Queensland.

MacGill was suspended until November 2 for breaching the code of conduct after blowing up at an umpire at a Sydney club game the weekend before last.

A three-man appeals tribunal, headed by former Sydney Cricket Association member Jim Tait and also including Larry King QC and former magistrate Craig Thompson, adjudicated on the appeal at Cricket NSW headquarters.

While MacGill pleaded guilty to the charge, he appealed against the severity of the sentence in the hope of making himself available for this week's game.

It is understood MacGill did not have to appear before the panel.

The ban will prevent him from playing in the four-day Pura Cup game starting on Friday against Queensland at the Gabba, where the first Ashes Test will be played next month.

The suspension will also keep the 35-year-old wrist-spinner out of the Blues' Ford Ranger Cup clash with the Bulls at the same venue on Wednesday.

MacGill, who has taken 11 wickets at an average of 26 in his three Test appearances at the Gabba, needs only two more victims to reach the 200 mark in Test cricket.

He pleaded guilty to disorderly and improper conduct after being reported by the umpires following the match against Campbelltown-Camden at University Oval.

Despite missing this week's matches in Brisbane, MacGill will still have a further Pura Cup match against South Australia in Adelaide to press his Test claims, while NSW is also scheduled to host England in a tour match at the SCG in mid November.

The veteran spinner made a decent start to the first class season with figures of 1-98 and 4-46 in the draw against South Australia at the SCG last week.
