Chargers defensive tackle Antonio Garay has been fined $15,000 for hitting Patriots quarterback Tom Brady below the knee last Sunday, according to a source. The incident happened in the third quarter of New England's 35-21 victory when Garay reached out his left arm into Brady's left knee. Brady, who escaped unscathed, on Monday credited the brace he was wearing on the knee for protecting him from a potentially devastating injury. "I'm glad I had a knee brace on," Brady said. "Those are scary when you've been through those ones before. He got me in a good spot and I'm glad the knee brace took the brunt of the force. Why I never wore a knee brace before (his season-ending ACL injury in 2008) I have no idea and why every quarterback doesn't wear one on their left knee I have no idea. It's just so unprotected."
