(CNN) -- African football champions TP Mazembe have been thrown out of the continent's Champions League competition after fielding an ineligible player. 

Tanzanian team Simba complained after the Congolese side included defender Janvier Bokungu in a second-round tie, which Mazembe won after triumphing in both legs. 

Mazembe then beat Morocco's Widad de Casablanca in the third round to reach the group stages of the tournament, which the club also won in 2009. 

The Confederation of African Football said in a statement on Saturday that Simba and Widad would play off at a neutral venue next week, with the winning team to take Mazembe's place in the eight-club group phase starting in July.

"Following a complaint filed by Simba Sports of Tanzania following match 68 of the Orange Champions League, the Confederation of African Football launched an investigation on the eligibility of TP Mazembe's player named Janvier Besala Bokungu," it said on its website. 

"The findings of the investigation were submitted to the Organizing Committee for CAF Interclubs Competitions. Based on those findings, the committee decided to disqualify TP Mazembe on the basis of Chapter VIII (Fraud), article 24, article 26 (Qualification of players) and article 29 of Orange CAF Champions League regulations." 

Simba had complained that the 22-year-old Bokungu was still contracted to Tunisian team Esperance, where he moved from Mazembe in 2007. 

He has played at international level for the Democratic Republic of Congo.
