Did Lou Duva actually jump on the apron when Chavez knocked Meldrick Taylor down?

I've heard this said but I haven't seen any footage or photos of Lou on the apron. Is there any evidence at all that Lou was on the apron? I mean hard evidence we can see. Meldrick is looking over that way but how do we know Lou was on the apron and it's not just some excuse that was being used? I'm not saying I don't think it happened, I'd just like to see some evidence, of any sort.

 

So there is no evidence? This is the thing about boxing fights, you have to actually watch them yourself to get the real lowdown.
