Charlton Athletic's development squad defender Ayo Obileye has signed a new contract with the Championship club.
The 20-year-old's previous deal had been due to expire next month.
However, under the terms of the fresh deal, Obileye will remain at The Valley for a further 12 months.
The centre-back, who joined Charlton from Sheffield Wednesday last October, spent part of last season on loan with League Two side Dagenham & Redbridge.
