UFC 146's revolving door still heavy

Cain Velasquez in a scene from the MMA documentary on Jon Fitch entitled "Some Great Heights."
Here's a look at what this Saturday's UFC 146 main card was originally constructed as back in March:
| Junior Dos Santos | vs. | Alistair Overem |
| Cain Velasquez | vs. | Frank Mir |
| Roy Nelson | vs. | Antonio Silva |
| Gabriel Gonzaga | vs. | Shane Del Rosario |
| Stefan Struve | vs. | Mark Hunt |
Now, three days shy of fight night, we've got a slightly different lineup. And by slightly different, we mean quite radically different. Overeem's drug-related suspension caused a switch to the main event, which trickled down a level or two. Injuries did their part, as well.
The new matchups are in bold, and the entirely new fighters are in bold italics.
| Junior Dos Santos | vs. | Frank Mir |
| Cain Velasquez | vs. | Antonio Silva |
| Roy Nelson | vs. | Dave Herman |
| Stipe Miocic | vs. | Shane Del Rosario |
| Stefan Struve | vs. | Lavar Johnson |
