The Court of Arbitration for Sport have granted Carlos Queiroz's request to have his six-month suspension imposed by the Portuguese Anti-Doping Agency lifted pending the outcome of his appeal.
The former Portugal coach was handed the sanction - which prevented him from working in Portugal - for alleged misbehaviour during an anti-doping testing session before the World Cup.
He was then sacked two days after Portugal suffered a surprise 1-0 defeat to Norway in Euro 2012 qualifying earlier this month.
The ruling from the CAS, however, means he is free to work until the appeal hearing, which CAS do not expect to take place before mid-November.
The suspension may resume at a later stage, if Queiroz's appeal is dismissed by the CAS.
