Ultimate Fighting Championship (UFC) lightweight Isaac Vallie-Flagg has been injured and forced to withdraw from his UFC 161 prelims bout opposite Sam Stout, scheduled for the MTS Centre in Winnipeg, Manitoba, Canada, on June 15, 2013.
Krause (19-4) is currently riding a seven-fight winning streak and was last seen outpointing Toby Imada in the main event of Resurrection Fighting Alliance (RFA) 6 last January. Stout (19-8-1), meanwhile, will look to make it two in a row after his split decision win over Caros Fodor at UFC 157 back in February.
UFC 161 will feature former UFC Light Heavyweight Champion Rashad Evans, as he looks to rebound from his career-worst two-fight losing streak when he takes on former two-division PRIDE champion Dan Henderson in a high-stakes affair.
The night's co-main event will see two more of the world's top 205-pound fighters go to war, as Antonio Rogerio Nogueira looks to build momentum from his UFC 156 upset over Evans when he takes on former division champion Mauricio Rua in a rematch of their 2005 "Fight of the Year," which "Shogun" won by decision.
