WINNIPEG –  Mitch Clarke and John Maguire might be backed into a corner, and only one of them is getting out after Saturday. Each with two straight losses, they’re in what can only be described these days as critical territory going into UFC 161, which takes place at MTS Centre in Winnipeg, Manitoba, Canada. But for Clarke (9-2 MMA, 0-2 UFC), tell him he’s backed in a corner all you want. He’s not about to walk into his fight with Maguire (18-5 MMA, 2-2 UFC) with a bad attitude. “You can’t go in thinking negative, in my opinion,” Clarke on Wednesday told MMAjunkie.com (www.mmajunkie.com) after a short workout for fans in Winnipeg.
