Nate Diaz -- Top UFC Fighter Asks for Shot ... I'll Replace McGregor!!! (VIDEO)

That didn't take long ... now that Conor McGregor's been axed from UFC 200, a big time fighter is publicly angling to take his spot ... with UFC fighter Tyron Woodley saying he's down to face Nate Diaz.

Woodley is #3 in the UFC Welterweight rankings -- aka no slouch -- and when we got him out in L.A., he told us he's already campaigning Dana White to give him a shot against Diaz.
