New England quarterback Tom Brady has worn a DonJoy Defiance custom knee brace on his left knee since his season-ending injury in 2008. Ever since that incident, the NFL has made it a violation to tackle quarterbacks below the knee. Some even call it the "Tom Brady Rule".

This past Sunday versus the Chargers, Brady nearly experienced the same injury as San Diego's Antonio Garay tackled him on a low hit to his left knee. Brade escaped unscathed from the incident.

Brady spoke with WEEI sports radio and credits his knee brace for protecting him during the incident. "I'm glad I had a knee brace on. Those are scary, man, 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, I have no idea. Why every quarterback doesn't wear one on their left knee, I have no idea. It's just so unprotected."
