Zynga has confirmed that chief operating officer John Schappert has resigned.
"We can confirm that John Schappert has left Zynga and its Board of Directors effective immediately," Mark Pincus, CEO and founder of Zynga, said in a statement. "John has made significant contributions to the games industry throughout his career and we appreciate all that he has done for Zynga. John leaves as a friend of the company and we wish him all the best."
The company disclosed his departure in a filing with the Securities and Exchange Commission.
The announcement comes shortly after Zynga announced a shake-up that saw Schappert relinquish his role as head of game development to two other execs, according to Reuters.
It's been a tough few weeks for Zynga. Disappointing second-quarter earnings resulted in a shareholder lawsuit that accused the gaming firm of failing to warn them about declining revenue.
Meanwhile, Electronic Arts sued Zynga for copyright infringement last week, alleging that Zynga's recently released Facebook game The Ville copied EA's The Sims Social.
