Bill Walker getting an MRI on his knee

Boston Globe
Swingman Bill Walker left practice Wednesday and is headed for Boston to get an MRI on his surgically repaired right knee. Walker tore his left ACL while at Kansas State and then hurt the right knee in a workout with the Golden State Warriors in July 2008 and then had surgery a few weeks later.
I really think we could use another backup 3 to keep Pierce's minutes down. Would have been nice to grab a guy like Keth Bogans, who recently signed with the Spurs. I'm assuming Danny still has confidence in Tony (insert one of those rolling eyes things).
