It appears that several players, including Shola Ameobi, Jamel Saihi, Alain Traoré, Razak Boukari, Guy Demel, Jordan Ayew, Michael Essien, Sulley Muntari, and Emmanuel Adebayor, will not be participating in the 2013 Africa Cup of Nations (CAN). The reasons range from club decisions, injuries, surgeries, or personal choices.
For the most accurate and up-to-date information on the status of these players and any potential changes, I recommend checking official statements from the football clubs, national football associations, or reputable sports news outlets. The availability of players for international competitions can be subject to changes based on various factors.
