The Scottish Football Association's disciplinary committee had been due to meet today but fresh snowfall in Glasgow prompted a postponement. No new date has yet been set for the meeting of the committee, who will determine Lennon's potential punishment for his dismissal in his side's Clydesdale Bank Premier League defeat by Hearts on November 10.
The Celtic manager was sent from the dugout on the advice of fourth official Steven McLean after complaining about referee Craig Thomson's failure to award his side a penalty for a handball by Ryan Stevenson.
The offence carries an automatic touchline ban, in Lennon's case of two matches, but Thomson's report also accused the former Celtic captain of "excessive misconduct".
The disciplinary committee will decide both the outcome of Lennon's appeal and any further sanctions resulting from the additional charge.
The panel will also discuss Lennon's actions after Gary Hooper struck a late winner against Dundee United on October 17. Tayside Police wrote to the SFA expressing concern about the way Lennon ran down the track to celebrate Hooper's goal in front of the stand housing visiting fans at Tannadice. The 39-year-old also faces more disciplinary action if another SFA committee decides he overstepped the mark with comments about Thomson following the Tynecastle clash, and criticism of referee Willie Collum following an earlier defeat by Rangers.
The general purposes committee had been due to meet at the beginning of last week, but snow forced that to be postponed too.
