Angle took proper care in training despite the neck injury. After advising with Dr. Andrews and the higher ups at WWE, the company asked him to take some time off from the original diagnosis to rest for the title match. On that note, considering it was WRESTLE-FREAKIN-MANIA, Kurt got the PPV payout as well.
Red seemed to ignore everyone's advice and kept working a full schedule despite the original injury. Going on an overseas tour after the first diagnosis only worsened the knee, especially with all of the airline travel.
No contest here, but this still is a bummer to find out about.
Angle currently has a knee/hamstring injury, yet keeps working through it and doesn't get anything done about it. That's what I was referring to.
