Tunisia key midfielder Youssef Msakni is struggling to be fit for Wednesday's Group D clash against Togo at the 2013 Africa Cup of Nations.

The Qatar-based attacking midfielder has been training alone ahead of the match because he is suffering from tonsilitis.

"All the team are fine, except Msakni, who had quite a serious case of tonsilitis," Tunisia coach Samir Trabelsi said.

"He trained alone with the doctor when we arrived here (Sunday). For Monday's session he trained with a group of injured players."

Msakni scored the late goal that sealed their 1-0 victory over Algeria, keeping alive their hopes of reaching the quarterfinals.

Togo and Tunisia have three points each in Group D, but the Hawks have the advantage thanks to a better goal difference.

Togo can advance to the quarterfinals if the match ends in a draw.
