The Austin Toros of the D-League have signed small forward Bill Walker.  

Walker (6-6, 235, Kansas State) was the 47th overall pick by the Washington Wizards in the 2008 NBA draft. He was then traded to the Boston Celtics. While on the Celtics roster, Walker was assigned to the NBA D-League, playing for the Utah Flash in 2008 and the Maine Red Claws in 2009.  

In three seasons (09-10 to 11-12), Walker played 120 games with the Knicks. Walker averaged 5.9 points and 2.5 rebounds in 19.4 minutes played his final season with New York.

The Maine Red Claws have acquired Kris Joseph.

Joseph, who was assigned to the Red Claws earlier this season by the Boston Celtics before being waived on Jan. 6, rejoins the team under an NBA Development League contract.

Joseph, 24, was selected by the Celtics in the 2nd round (51st overall) in the 2012 NBA Draft, appearing in six games with Boston. Joseph appeared in ten games on assignment with the Red Claws, averaging 17.7 points and 5.3 rebounds per game.
