Maboulou omitted from Congo AFCON squad
The Bastia defender was a surprise inclusion in Claude Le Roy's provisional 26-man party for the tournament in Equatorial Guinea.
However, Maboulou is said to have failed to show for a pre-tournament camp in Senegal and has been omitted from the squad.
Midfielders Scott Bitsindou and Jordan Massengo also miss out as Congo look to impress in a tournament they won back in 1972.
Congo last competed in the AFCON finals in 2000, when they finished bottom of Group D without scoring a goal.
Le Roy's men face Equatorial Guinea in the opening game of the competition in Bata a week on Saturday.
