Celtics' Trevion Williams: Inks deal with Boston

Williams signed a Summer League deal with the Celtics on Friday, Jonathan Givony of ESPN.com reports.

Williams went undrafted Thursday, but he'll still get a chance to compete for an NBA roster spot during Summer League. The 6-foot-10 forward averaged over 11.0 points and 7.0 rebounds in each of his final three seasons at Purdue.
