Lampre provisionally banned Diego Ulissi for a second time on Tuesday after the International Cycling Union opened disciplinary proceedings.
Ulissi, 25, was suspended by Lampre in June after testing positive for bronchodilator salbutamol at the Giro d'Italia, where he won two stages.
Lampre allowed the Italian cyclist to return for Tuesday's Coppa Bernocchi and he finished 22nd at the event.
However, Lampre announced Ulissi's suspension just hours later.
"Immediately after the first race in which Diego Ulissi has taken part after his forced stop, the UCI notified the cyclist his referral to the disciplinary commission of Swiss Cycling," the team statement read.
"Finally, in the next weeks the rider and his team will have a final view about the long procedure concerning this topic.
"Respecting the internal health code of the team and the rules of MPCC, considering the referral, Ulissi won't take part in the next races."
Ulissi is facing a two-year ban if found guilty.
