Guys get injured/test positive fairly often but when was the last time a replacement pulled off the upset?

Khan/Garcia, maybe?

Manny Pacquiao when he whooped Lehlo Ledwaba is the one that comes to mind

Khan-Peterson 2 was meant to happen in March but Peterson popped so Khan-Garcia was made for July. Technically he was a replacement but he had a full camp to prepare.

At HW? or in general? Wasn't Douglas a last minute replacement or a late stay busy fight for Tyson in Tokyo in Japan?

Actually, Khan/Peterson 2 was supposed to happen in May, not March.

Sanders beating Klitschko was a couple of years after that in heavy. He had 4 weeks notice I think in 2003
