French-born Constant was named on Wednesday in their squadfor the Aug.14 friendly against hosts Algeria in Blida.
Coach Michel Dussuyer, in a French television interview,said Constant had initiated the return and committed to "thelong term project" of the team.
Constant has not played for Guinea since September when hequit the team saying he was frustrated with the organisationaround the squad and poor relations with some of his team mates.
He had previously also sat out the 2012 African Nations Cupfinals in Equatorial Guinea and Gabon because of similarfrustrations.
Last month Constant walked off the pitch in a pre-seasonmatch between Milan and Sassuolo because of racist abuse.
