11:01am: Williams is close to signing with the Celtics, according to Washburn (via Twitter). He is expected to join the team and finalize a deal once he receives a clearance letter from his former Chinese team.

10:19am: In search of depth, the Celtics are "strongly considering" signing free agent swingman Terrence Williams to a 10-day contract, reports Gary Washburn of the Boston Globe (via Twitter).

Discussing potential roster moves for the Celtics in the wake of a handful of season-ending injuries, president Danny Ainge and coach Doc Rivers have both indicated that adding a player on a 10-day deal is likely as the team looks for a short-term fix. Rivers specifically noted that the Chinese Basketball Association's season was coming to an end soon, which was where Williams spent the majority of the year. Mark Deeks of ShamSports reported last week that Williams had returned stateside due to a death in the family.

Williams, 25, averaged 17.9 PPG in 29 games for the Guangdong Southern Tigers this season, according to Asia-Basket.com. The Louisville product has yet to deliver on the promise that got him picked 11th overall in the 2009 draft, but has shown flashes of potential in stints with the Nets, Rockets, and Kings. In 129 career NBA games, he has recorded 7.6 PPG and an 11.4 PER.
