Tim Duncan has been told that the left knee brace he wears prevented his ACL from tearing on Feb. 2. It looked really bad when Wizards G Martell Webster rolled into Duncan's legs from behind. But he escaped with knee/ankle sprains and ended up missing just four games. "I was in a lot of pain and had no concept of time frame," Duncan said Saturday. "I didn't know how long I'd be out or how I'd feel the next day. "I got lucky, so I'm here."
