John Sullivan

Charlton Athletic manager Chris Powell has confirmed Yado Mambo and John Sullivan will be released at the end of their contracts this summer.

Both defender Mambo and goalkeeper Sullivan have had loan spells away from the Valley this season.

Mambo spent time at AFC Wimbledon and Shrewsbury while Sullivan represented Colchester and also the Dons.

Powell informed the pair they would be unlikely to get regular first-team football next season.
