That video shows an athlete slowly hobbling round and at no point putting full force on her damaged leg because with a ruptured Achilles she is not able to. When you throw a right hand punch it's like doing a sprint start off your right foot and Haye was able to do that "when he got his breath back" after the 6th round which would be impossible with a ruptured right Achilles. She is only moved forward upright, basically walking, not launching forward throwing all her body weight in to right hands trying to knock someone out.

You all know it to be true
