Nigeria set up Uganda friendly after Bolivia 'chicken out'
Nigerian football officials have said Bolivia "chickened out" of an international friendly in the African country.
The nations were due to meet on 25 March but the South American country pulled out of the fixture citing security concerns.
Nigeria will now face Uganda instead in the south-eastern city of Uyo.
The Nigeria Football Federation said: "Bolivia chickened out at the eleventh hour despite signing a contract."
In a statement on its website, the NFF official Jairo Pachon added: "We certainly will have time to deal with the Bolivia matter in a few days, but our concentration has been on getting a replacement for them.
"Their excuses do not hold any water. But we have spoken to our lawyers and will approach Fifa on the matter."
Bolivia pulled out of the fixture because "armed conflict and the tense political situation in Nigeria" - Boko Haram, the Islamist militant group active in the north east of the country, has killed thousands of people in its drive to establish an Islamic state.
Nigerian officials said everything was in place to ensure a hitch-free game.
Super Eagles goalkeeper Vincent Enyeama will win his 100th cap if he features against the Cranes.
