With their respective opponents sidelined due to injuries, former Strikeforce women’s bantamweight champion Sarah Kaufman and Brazilian knockout artist Amanda Nunes find themselves on opposing sides of the octagon at The Ultimate Fighter Nations Finale. The event is set for April 16 in Quebec City, Quebec, Canada. Seeking her first UFC victory, Kaufman (16-2 MMA, 0-0 UFC) was originally slated to face off against submission specialist Shayna Baszler on the TUF Nations Finale card. The pair first met under the Strikeforce banner in June 2009 when Kaufman earned a close decision victory. However, a training injury forced Baszler to withdraw from the planned rematch this week, leaving Kaufman without an opponent for the second time in her brief UFC career.
