Shane Carwin confirmed on his official website today that Brock Lesnar will be unable to defend his title at UFC 108 on January 2 in Las Vegas, delaying the matchup that was originally scheduled for UFC 106 once again.

“My manager Jason Genet just told me that UFC 108 is not happening,” wrote Carwin. “Brock has Mono and what the UFC has told me is that I have earned the title shott but I have to wait for the title holder. I hope Brock gets well soon.”
