World Cup 2014: Nigeria's Ahmed Musa & Elderson Echiejile injured

 Nigeria duo Elderson Echiejile and Ahmed Musa have injury worries just a week before the start of the World Cup.

Echiejile has a suspected hamstring strain and will miss Saturday's final friendly against USA in Florida before the team heads for Brazil.

Super Eagles coach Stephen Keshi intends to give the Monaco defender as long as possible to prove his fitness.

"The doctors have an appointment for an MRI scan for Elderson to know the extent of the problem," said Keshi.  "We will know exactly what the problem is and where we go from there."

CSKA Moscow winger Musa is a doubt to face USA with a thigh strain.

Nigeria have until 24 hours before their opening game against Iran on 16 June to replace any injured players. http://www.bbc.com/sport/0/football/27730012
