Cervi made his professional debut in the Legadue in 2010, playing two minutes without statistics in his only game that season. He signed his first professional contract, a five-year deal, with Reggio in November 2010, also being incorporated into the first squad that season. In 2011-12 he contributed 4.5 points, 4.5 rebounds and a league best 2.2 blocks in 16.6 minutes per game, helping his side earn a promotion to the first divisionSerie A. For his prowess he was selected as the Legadue's best Italian player. His contract with the side was renegotiated, while the length stayed the same, his salary was increased and an annual NBAescape clause inserted. After having major knee surgery over the summer, Cervi had a difficult start in his first Serie A season whilst also struggling to change his shooting technique. He improved in the last months of the 2012-13 season and was one of the best Reggio players in the playoff series against Acea Roma. After a slow start in 2013-14, he finished the season as a starter, contributing 9 points, 4.2 rebounds and 1.2 blocks per game in the closely fought playoff series against holders Montepaschi Siena. The same season he posted 3.8 points, 3.6 rebounds and 1.1 blocks in around 14 minutes per game in the European third tier 2013–14 EuroChallenge, including 7 points, 5 rebounds and 2 blocks in the final, to help Reggio Emilia win the title. The EuroChallenge title gave Reggio Emilia the chance to play in the second tier 2014-15 Eurocup where Cervi posted 5.6 points, 4.3 rebounds and 1.2 blocks as the side exited at the group stage. He finished as the second best shot blocker of the 2014-15 Serie A with 1.8 per game. In July 2015 he joined EA7 Emporio Armani Milano, signing a two-year deal with the EuroLeague-playing side. However, only a few days after the announcement Milan decided to exercise a clause in his contract to release the player. He then signed with another Serie A side, Sidigas Avellino on 29 July.
International career
Cervi played with the Italy Under-20 squad in the 2011 European Championship, posting 4.2 points, 2.1 rebounds and 1.4 blocks as the side came home with a silver medal. He was part of the Italy B squad that finished 5th at the 2013 Mediterranean Games. Cervi would make his full international debut for Italy against Germany in July 2014. At 2.16 m, Cervi is an intimidating presence in the paint, a rare characteristic for an Italian, as such he has regularly been called up to Italy squads. He took part in the successful qualification for EuroBasket 2015, with 3.8 points, 3.5 rebounds and 2.8 blocks in 13 minutes per game. The center was called to the preliminary squad for the competition in June 2015, but he did not make the final cut.
