Nigeria coach Stephen Keshi has selection problems ahead of his team's second Group F match with Bosnia-Herzegovina on Saturday night.
Keshi witnessed his side struggle to a 0-0 draw with Iran on Monday evening, and their bid to reach the last 16 hasn't been helped after Godfrey Oboabona was ruled out with an ankle injury.
Three other players - Kenneth Omeruo, Ahmed Musa and Reuben Gabriel - could also be absent as Nigeria look for a result that could potentially eliminate Bosnia from the tournament.
Bosnia impressed against Argentina on their World Cup debut at the Maracana on Sunday night before eventually falling to defeat, but coach Safet Susic could take the positives from his team's performance.
Vedad Ibisevic came off the bench in the latter stages of that match to move himself into contention for a starting role, and he could be the sole change in an otherwise identical lineup.
