Anderson Silva lost to Chris Weidman for the second time in a row, only this time it was due to a horrific injury.
Silva broke his leg trying to kick Weidman in the second round of their fight at UFC 168. Silva obviously was unable to continue and lost by TKO.

After the fight, Weidman paid his respects to Silva.

“Regardless of what happened in this fight, he’s still known as the greatest of all-time.”
Silva had to be stretchered out of the arena:
Weidman had Silva on his back during the first round and appeared to be leading in the fight until the injury. Hopefully this brutal broken leg will not end Silva’s career.
