Neil Davidson of the Canadian Press shared the fight card update via Twitter.com earlier this evening.
Lentz was on a four-fight win streak before eating an illegal knee from Charles Oliveira at UFC on Versus 4, which dazed "The Carny" long enough for the Brazilian to take his back and slip in a fight-ending rear naked choke. The Pennsylvania Athletic Commission, however, later overturned the result after watching the replay and ruled it a "No Contest."
Bocek, meanwhile, was on the receiving end of a Ben Henderson rout in his most recent performance, losing to "Smooth" via lopsided unanimous decision. The Brazilian jiu-jitsu specialist has won just one fight in his last three appearances, a submission over Dustin Hazelett at UFC 124 back in Dec. 2010.
UFC 140 is expected feature a rematch between two former heavyweight champions, Frank Mir vs. Antonio Rodrigo Nogueira, and "Big Nog's" brother, Antonio Rogerio Nogueira, taking on Tito Ortiz in a light heavyweight showdown.
