Ugly scenes marred the end of the teams' last league meeting in August
Nottingham Forest supporters have been urged not to travel to Saturday's league clash with Derby County if they do not have a ticket.
Forest have sold their 2,000 seat allocation for the fixture which kicks off at Pride Park at 1300 GMT.
Derby County have also urged home fans without a ticket to avoid travelling to the stadium as the home seating is also sold out.
The Rams are looking to end Forest's 19 match unbeaten run in the Championship.
Both clubs were fined by the Football Association after trouble flared between players following their last league meeting at the City Ground in August, which Forest won 3-2.
Forest's Nathan Tyson was handed a two-game suspended ban and a £5,000 fine after pleading guilty to an FA charge of improper conduct.
He ran across the pitch with a corner flag following the final whistle.
