Oboabona had missed the Super Eagles second Group match against Bosnia-Herzegovina due to the injury he sustained in the opening group match.
The statement said the team started training for Wednesday’s group decider against former world champions, Argentina, immediately it settled down in Porto Alegre.
Meanwhile, the Captain of the team, Joseph Yobo, was quoted as saying he preferred a win on Wednesday to his much advertised attainment of 100 caps if featured in the match against Argentina.
“It is good news that I will reach that milestone, but what is uppermost in my mind is for the team to win and for us to advance to the next stage.
“The rest will be a bonus”, Yobo was quoted as saying. (NAN)
