Napoli coach Walter Mazzarri has had his touchline ban temporarily lifted by the Court of Arbitration for Sport and will take his place on the bench for the Champions League match against Chelsea on Wednesday.
Mazzarri was handed a two-match ban for "improper conduct" after he pushed Villarreal forward Nilmar to protest time-wasting tactics during a group match in December.
Napoli appealed to CAS, which says it has agreed to temporarily lift the ban while it studies the full case.
Mazzarri watched Napoli beat Chelsea 3-1 in the first leg of the last 16 on television. The second leg is on Wednesday.
UEFA turned down Napoli's appeals last month and added a third match to the sanction. The additional ban was deferred for a two-year probationary period.
