Poirier, who saw limited playing time last season, will make $2.62MM next season. He can be a restricted free agent after next season if Oklahoma City extends a $3.27MM qualifying offer.
Boston gives itself a little more cap flexibility with the move. In 22 games during his first NBA season, Poirier averaged 1.9 PPG in 5.9 MPG. He only played a total of 130 minutes.
Poirier led the Euro League in rebounding during the 2018/19 season with Baskonia of the Spanish Liga ACB.
