Italian prop Ceccarelli signs for Edinburgh
The 26-year-old – who made his international debut in the 2016 Six Nations – signed a one year deal after spending just one season at Oyonnax.
"I'm really excited for this new experience," Ceccarelli told the club website.
"The Pro14 is a competition that I know well [he played for Zebre from 2015-2017], but this new challenge in a different country, with a different rugby culture, will only make me a better rugby player."
Edinburgh head coach Richard Cockerill said Ceccarelli would spice up competition for places.
"Pietro is a combatable tighthead who's had experience playing in both the French Top 14 and on the international stage," said Cockerill.
"His arrival next season will only add to our strength and depth in the front-row."
