As expected, Ray Allen will go under the knife this week to remove bone spurs from his right ankle. Reports the Boston Herald: “Allen will have surgery to remove bone spurs from the ankle at 6 a.m. on Wednesday at New England Baptist Hospital, according to a source. The problem, which first surfaced during in Los Angeles during the C’s’ eight-game road trip in mid-March, eventually forced Allen to miss 15 regular-season games as well as the first two games of the Celtics’ first-round playoff series against Atlanta. By Allen’s own admission, the ankle had a serious impact on his ability to cut, plant and rise for his fabled jump shot. It even affected his free throw form. Allen finished the playoffs 32-for-45 (.726) from the line — a career postseason low. He did, however, show considerable improvement late in the conference finals against Miami from all spots on the floor. He scored 15 points on 5-for-11 shooting, including three 3-pointers, in Game 7, and was 8-for-8 from the line in Game 5. But with a big summer of free agency looming, Allen vowed to take care of his ankle trouble as quickly as possible.”
