The Boston Celtics have agreed to sign Vincent Poirier.

Poirier joins the NBA after spending the last six seasons playing professionally overseas, most recently with Kirolbet Baskonia Vitoria-Gasteiz in 2018-19 where he averaged 10.5 points (61.6% FG), 7.3 rebounds, 1.1 assists, and 1.0 blocked shots in 73 games (59 starts) across the Euroleague and Spanish ACB. He ranked third on his Baskonia team in scoring, while also leading the team in rebounding.
