"Nigeria will play against Guatemala on February 9. That will begin the rebuilding process of the team," disclosed general secretary of the Nigeria Football Federation (NFF), Musa Amadu.
Nigeria are ranked 32nd in the world, while Guatemala are a lowly 118. It will be the first-ever meeting between the two countries at this level.
The match will also be Siasia's first in charge since he was appointed Nigeria coach in December on a four-year contract.
The Super Eagles will also use the game to prepare for a 2012 Nations Cup qualifier at home to Ethiopia at the end of March.
Nigeria are three points behind Group B leaders Guinea in the qualifying series, which also has Madagascar with only the overall group winners guaranteed a ticket to the final tournament next year.
