Fedor last bout was recently against arguably the best middleweight (185 lbs) Matt Lindland.
Lindland beefed up to 212 lbs. for their fight but was still 18 lbs. lighter than Fedor. Surprisingly, the Olympic Silver Medalist drew first blood by cutting Fedor with a left hook. It didn't faze the Russian but Lindland was able to grab with underhooks and attempted a takedown. The Russian grabbed the ropes which prevented the takedown. A few more attempts resulted in the same action. Lindland tried again but this time Fedor didn't grab the ropes but was able to reverse and ended up on top. It was goodnight after that since he caught Lindland with an armbar. There is a little controversy with the rope grabbing but everyone is in agreement that it would not have made any difference to the outcome of the fight.
