Two-time Masters champion Bernhard Langer, 66, has announced that he will be having surgery on a torn Achilles tendon that he sustained in training. Although the German's participation in this year's Masters was already scheduled to be his last, he is unlikely to be present at Augusta National due to the lengthy recovery process of at least four months. Langer had stated recently that this year's Masters would be his last, making the absence all the more poignant, and putting his plans for the remainder of the PGA Tour Champions season in jeopardy. The German is the winningest golfer in PGA Tour Champions history, claiming 46 victories on the circuit.
