Many are suspecting that he quit mentally and faked the injury to save face. I wouldn't be surprised because he already lost the 100m against a 35 year old grandpa who is hated for like 2 botched drug tests, and another guy nobody has ever heard of.
He could have made history and broke a lot of records in London. Instead he only got a bronze medal and ended up taken off the field crying on a stretcher Fitting ending to his arrogance and lack of discipline.
