UFC heavyweight champion Brock Lesnar , No. 1 contender Cain Velasquez , undercard fighters Jake Shields Matt Hamill and Tito Ortiz , along with UFC President Dana White, will all meet the media on Wednesday at the UFC 121 pre-fight press conference. And if you can't be there at the Walt Disney Concert Hall in Los Angeles, you can watch it live right here at MMAFighting.com.The press conference is open to the public, and it will be a good opportunity to see how the fans in Los Angeles react to Lesnar and Velasquez. Although Lesnar is the UFC's biggest draw, he's something of a villain to many fans. Velasquez, on the other hand, is a quiet, soft-spoken and likable guy who has been marketed heavily in Southern California by the UFC. So expect Velasquez to get the cheers from the crowd.The press conference begins at 5 PM ET and the video is below.
