It's fight week, and with official pre-event activities still a day away, let's kill a morning with some free fights.
Ahead of Saturday's UFC 148 event in Las Vegas, the UFC has released a series of free fight videos featuring the card's four co-headliners.
They feature UFC middleweight champion Anderson Silva and challenger Chael Sonnen, as well as co-headliners Forrest Griffin and Tito Ortiz, who meet in a rubber match.
UFC 148 takes place Saturday at MGM Grand Garden Arena in Las Vegas. The pay-per-view main card follows prelims on FX and Facebook.
The featured video above pits Silva against PRIDE import Dan Henderson. The UFC 82 champion-vs.-champion bout took place in 2008 and marked Silva's third attempted title defense after wins over Nate Marquardt and Rich Franklin.
