Top 10 Scariest Finishes in UFC History | News, Scores, Highlights, Stats, and Rumors

The UFC likes to give fans a very rosy picture of cagefighting. While it's an inherently ugly sport, the promotion cleans things up to the point where fans don't have to feel guilty about what they're watching. That results in videos like this ending up on the UFC's YouTube channel, while videos like this get aggressively taken down by copyright claims.

Sometimes, though, things slip through the cracks. Sometimes, a terrible injury isn't immediately obvious to the production crew. And sometimes, fans get to see the reality of MMA.

That was the case at UFC 168, which ended with longtime middleweight champion Anderson Silva screaming on the canvas.

After being outworked in the first round of his bout with Chris Weidman, the Spider upped his volume in the second using the tool he had found the most success with: leg kicks. After drilling one hard to Weidman's thigh, Silva began throwing them with confidence...a bit too much confidence.

Weidman made the adjustment, checking Silva's second kick with his shin and then checking the third with his knee. An agonizing snap rang across the arena on contact, and Silva fell back, clutching his leg.

The cameras followed a celebrating Weidman, then turned to Silva, visibly and audibly dealing with some of the worst pain imaginable.

When the replays began running and the severity of Silva's injury (a broken tibia and fibula) became obvious, the UFC went about its normal approach, keeping the camera fixed squarely on Weidman and ensuring fans were as ignorant as possible of what had happened.

Still, the damage was done and the image of Silva's foot dangling from the rest of his leg was burned into the memories of fans.
