Rookie Avery Bradley had surgery on his left ankle last month and his rehab is going well. "I'm just trying to recover," Bradley told ESPNBoston.com Thursday. "I'm doing rehab, lifting weights, trying to get back as fast as possible. It's been real good. I'm able to walk now. I'm getting better every single day." Bradley sprained the ankle when he was working out for the Oklahoma City Thunder in mid-June. "It's real frustrating, just the injury itself," said Bradley. "I've never been injured before, so having to sit out and not being able to play [in the summer league] was hard for me."
