Mitch Clarke had his back against the wall a week ago, and he knew it. The Canadian had two straight losses, and they happened to come in his only two UFC fights. Going 0-2 in the UFC these days usually gets you a pink slip. Going 0-3 is pretty much a certainty. So that had Clarke (10-2 MMA, 1-2 UFC) plenty motivated for his UFC 161 fight in Winnipeg a week ago against John Maguire (18-6 MMA, 2-3 UFC)
