Royce Gracie vs Wanderlei Silva?

[D241]

Has anyone seen this fight or can give me the background? Sherdog's fight finder doesn't show them as ever fighting each other, not even a no contest. I found the only clip I could which seems incomplete, maybe it's not Royce, but can we have some clarification?
I would just pm IlostmyDog, but then I wouldn't get to show off my new avatar and sig courtesy of BDW as well as maybe others didn't know about this clip such as myself.

That's not Royce, it's Marcelao Barbosa

Definitely not Royce Gracie.
I can't tell for sure who it is from the footage, but it definitely looks like a late 1990's Wanderlei, before he ended up in UFC the first time.
I'm thinking it's footage from when he fought Brazilian Vale Tudo, or International Vale Tudo.

And it looks like I was right, this is back from Brazilian Vale Tudo.
Thanks Onion for clearing that up, I was too lazy.
