Feyenoord have confirmed they will appeal to the Court of Arbitration for Sport over UEFA's decision to exclude them from the UEFA Cup following crowd trouble at a match against Nancy earlier in the season.
European football's governing body handed down the punishment last week, having appealed against their own original verdict of a fine.
The Dutch club's decision mean Tottenham's bye into the last 16 of the competition is dependent on the outcome of the appeal.
'We want to let CAS test if the verdict of the appeal committee is correct, because we feel that Feyenood have been unjustly treated with this punishment,' Feyenoord financial director Onno Jacobs said on the club's official website.
'During the appeal we will continue to prepare for the games against Tottenham, but we will also ask CAS for a swift decision.'
Spurs were due to travel to Rotterdam on February 15 and, if Feyenoord's appeal fails, they will go straight through to the next round where they will play Braga or Parma.
