A new lightweight bout has been added to UFC 161. James Krause, a former WEC figther and The Ultimate Fighter hopeful, has agreed to meet Sam Stout on June 15 after Isaac Vallie-Flagg, Stout’s original opponent, pulled out of the bout due to an injury. The 155-pound bout will air on the FX prelims. Krause (19-4) returns to Zuffa riding a seven-fight winning streak. He went 0-2 in WEC in 2009 and failed to be a part of TUF: Live last year when he lost to Justin Lawrence via first-round TKO in the preliminary round. Stout (20-8-1) is 2-2 in his last four fights. He most recently defeated Caros Fodor via split decision at UFC 157 in February. Vallie-Flagg tweeted on Wednesday that a compressed disc in his back and torn muscle in his hip caused him to withdraw from the fight. He added that he is waiting to hear if the injuries will require surgery, and as a result, he doesn’t know how long he will be sidelined for. UFC 161, headlined by Rashad Evans vs. Dan Henderson, will take place at the MTS Centre in Winnipeg, Manitoba, Canada.
