Mir returned to the UFC a year and a half later, however wasn't the same. He lost to newcomer Márcio Cruz at UFC 57: Liddell vs. Couture 3 on February 4, 2006. Since then he has been inconsistent, scoring an umimpressive victory over Dan Christison at UFC 61: Bitter Rivals and a TKO loss to Brandon Vera at UFC 65: Bad Intentions. His last fight was a submission victory over Antoni Hardonk at UFC 74: Respect on August 25, 2007.

Picking a winner is tough in this fight. How Lesnar will fare against Mir is anyone's guess. When Lesnar was in WWE, he and Kurt Angle had a friendly wrestling match backstage and Angle was said to have had little trouble handling Lesnar, despite Angle not having trained for years and being older than Lesnar. However as we reported earlier this week, Nick Thompson recently trained with Lesnar and was very impressed with him, saying that "he's going to go far in this sport. I think that begins on February 2" (for the full article, click here). Mir has been inconsistent since his return from his accident and a lot depends on what kind of shape Mir will show up in.

Another question is what will happen if Lesnar loses, and if he were to lose his subsequent fights. Lesnar was a top WWE star when he quit due to hating the travel. When Lesnar wasn't signed for the regular season with the Minnesota Vikings, instead of going to NFL Europe and improving on his skills, he quit pro football altogether. A couple of early losses could cut Lesnar's MMA aspiratings, and UFC's hopes, short.
