BOSTON (AP) – The Boston Celtics have signed second-round draft pick Bill Walker.

Celtics general manager Danny Ainge praised Walker’s “hard work and skill development” over the summer in announcing the signing Friday.

The Celtics obtained rights to the 6-6 forward out of Kansas State in exchange for cash after he was chosen with the 47th pick by Washington in this year’s NBA draft.

Walker had minor arthroscopic surgery on his right knee last month after injuring it in a pre-draft workout in June. He missed the Celtics’ rookie camp. He had surgery on the same knee as a high school freshman.

In two seasons with the Wildcats, Walker averaged 15.3 points and 6.0 rebounds in 37 games.

Terms of the deal were not announced.

C’s sign Miles

The Boston Celtics signed forward Darius Miles, who missed the last two NBA seasons because of knee injuries.

Celtics general manager Danny Ainge said Friday that Miles worked out twice for the team before signing.

Miles played for Portland in the 2005-2006 season. Portland waived Miles after it was determined his right knee was damaged enough to qualify as a career-ending injury.

Miles was selected third overall by the Los Angeles Clippers in the 2000 NBA draft.
