Ex-caddie suggests Tiger's injuries self-inflicted

According to his former caddie Steve Williams, Tiger Woods' long-term injuries might have been self-inflicted due to his intense training regimen.

"I don't doubt Tiger will come back to the winner's circle," Williams said in an interview with the BBC.

"But whether he comes back and wins more major championships? That's going to be a very difficult task," said the New Zealander.
