Hamburg, Germany – Hamburg announced on Wednesday that the day period.
Cardoso has taken charge of Hamburg's last two matches since the departure of former boss Michael Oenning, but under league rules, he is unable to keep his current position for longer than 15 days because he does not hold a suitable coaching license.
The DFB confirmed that it would not make an exception for Cardoso, meaning that if Hamburg's appeal is turned down, one possible solution would be for the club's director of sport, Frank Arnesen, to take over because he owns the required license.
