Thoughts on Elvis meeting Ali in 1974?

There had to be at least two meetings...right??..
I've seen two photos...one formal..Ali with a suit/tie on...and the other one...Elvis and Ali sparring...any others??
any thoughts on this from anyone??

Elvis gave Muhammad Ali a beautiful robe....(see photo below)
