From ESPN.com's Marc Stein:
Hearing Celts discussing 10-day deal with Roddy Beaubois. Mavs dreamed he'd become Pocket Rajon Rondo; now maybe he'll understudy Real Rondo
— Marc Stein (@ESPNSteinLine) February 26, 2014
The 26-year-old Beaubois, a native of Guadeloupe, spent four seasons with the Mavericks. He's averaged 7.1 points, 2.1 assists, and 1.9 rebounds over 15.9 minutes per game during his career.
[Update: Before Wednesday's game, Celtics coach Brad Stevens was asked about Beaubois and noted, "I’ve heard [his name]; that’s certainly been brought up. But from what I know, nothing imminent, nothing cemented."]
