Kemba Walker: Undergoes successful knee surgery

Walker missed the final two games of the 2016-17 season with a knee injury,
which likely prompted the offseason procedure. The recovery time for such a
surgery is usually around six weeks, so he should be back to basketball
activities around late June. Last season, he averaged 23.2 points and 5.5
assists while shooting 44.4 percent from the field and 39.9 percent from beyond
the arc.
