Rangers manager Walter Smith has been handed a four-match touchline ban for ''adopting a threatening and aggressive attitude'' in Saturday's Premier League game at Kilmarnock, the Scottish Football Association have confirmed.
His dugout ban will kick in from October 3, which means he will be in the stand for the Old Firm encounter against Celtic the following day, but has until September 30 to appeal.
He was sent to the stand after reacting angrily when a red card was shown to Rangers midfielder Pedro Mendes and he confronted Kilmarnock striker Connor Sammon, who he believed had been encouraging the referee to send off the Rangers player.
Sammon insisted that he had actually been appealing for the official to play advantage.
The Rangers manager later admitted that he should not have reacted the way he did and said he was unlikely to appeal against any punishment decided by the SFA disciplinary committee.
Under the SFA's disciplinary rules, Smith faced an automatic two-match touchline ban beginning 14 days from the incident in question. However, two games are added to the punishment for every prior case of misconduct during the previous three years.
Smith served a two-match ban after being sent off in a Scottish Cup game against Hibernian in March 2008. His four-match suspension therefore sees the Ibrox boss sidelined from the Old Firm derby and SPL games against St Johnstone and Hibs, as well as the Co-operative Insurance Cup quarter-final at Dundee.
He will be allowed to return to the dugout for the November 1 league game at Dundee United.
