Tiger Woods' quest to win his third career FedEx Cup championship may have just taken a very painful turn south.
During his second round of The Barclays on Friday, Woods made an awkward swing off the teebox and immediately grimaced. He then doubled over in pain and clutched his left knee, which golf fans will remember was the same knee he had surgically repaired after tearing his ACL and breaking his left leg prior to the 2008 U.S. Open.
Woods also appears to be favoring his lower back, which would be a new injury on his career resume.
Woods has become a lightening rod for leg injuries since that time, most recently rupturing his Achilles tendon on the same left leg during rehabilitation for his repaired knee.
He has also infamously turned toward some... questionable medical treatments to expedite the healing process of his many injuries. Dr. Tony Galea, one of Canada's most prominent sports injury physicians, treated Woods with his patented "blood-spinning" treatments while Tiger was attempting to heal his Achilles tendon.
Shortly thereafter Galea was charged with illegally importing and selling drugs, including various forms of performance-enhancing drugs like human growth hormone. Many of Galea's clients also used the controversial substance Actovegin, which includes extract from calf's blood and has since been banned for medical use in Canada.
Woods has chosen to continue his second round at Bethpage Black, however is noticably in pain and is walking with a considerable limp. He remains at even par for the round and 3-under for the tournament, five shots back from leader Nick Watney.
