WINNIPEG – Stepping in to face Stipe Miocic on just three-weeks’ notice proved to be too much of a challenge for Roy Nelson, who saw a three-fight win streak snapped in a unanimous-decision loss. The heavyweight bout co-headlined today’s UFC 161 event at MTS Centre in Winnipeg. It aired on pay-per-view after prelims on FX and Facebook. Nelson, who stepped in on short notice to face Miocic to add star power to a card that lost its original main event, was never really in the fight. Miocic steered clear of the big right hand in the early going while looking for a few quick takedown attempts. Meanwhile, Nelson shucked off the moves and looked to deliver his trademark power punches. It was Miocic’s speed that proved the difference in the first, as he largely avoided taking any punches from “Big Country” while slipping and delivering countershots in bunches. Nelson appeared to tire as the round wore on, taking a few looks up at the clock
