No confirmation on which knee had surgery, my guess is right knee. He is wearing a patellar knee strap which helps distribute compression along the patellar tendon to alleviate pain which is below the kneecap. Injury/surgery performed in that location per reports. #BillsCamp https://t.co/PB42ss4Bfv
