Shittu in but Odemwingie out of Nigeria squad
A total of 32 players were named for a warm-up match against Catalunya in Barcelona on January 2 followed by a training camp in Portugal. It will be cut to 23 by January 9, the Nigerian football federation said on Saturday.
Odemwingie's exclusion continues a fractious relationship he has had with the Nigeria national team over the last 18 months and opens the door for Shola Ameobi, the former England Under-21 international who won his first cap for the Super Eagles in November.
Millwall's Shittu returns for the first time since being dropped last year.
Nigeria will compete against defending champions Zambia, Burkina Faso and Ethiopia in Group C at the Nations Cup finals in South Africa which start on January 19.
Only five players remain from Nigeria's squad at their last major tournament appearance at the 2010 World Cup finals, also in South Africa.
