Miller was recently left without an opponent for UFC 103 after Thiago Tavares was sidelined due to a knee injury suffered while training before Lopez was tabbed by the UFC as a replacement in the bout.
Miller has established himself as a legitimate contender in the UFC’s 155 pound division after putting together victories over the likes of David Baron, Matt Wiman, and most recently, Mac Danzig at UFC 100. His sole defeat in the octagon came in the form of a hard fought decision against fellow title contender Gray Maynard at UFC 96. The AMA Fight Club trained fighter holds a career record of 13-2, with nine of his wins coming by way of submission.
Lopez last saw action in October of 2008. He has a fought in a variety of promotions, putting together a career record of 12-1 with his only loss coming by way of split decision. He’s known as a well rounded fighter with dangerous striking ability. The bout against Miller will be a significant jump in competition for Lopez, but with a record of 12-1, it seems like a necessary leap.
