Rookie goalkeeper Nick Pope has signed a new contract at Charlton after making good progress with the League One leaders.
The 19-year-old, who was snapped up from Bury Town by manager Chris Powell last summer, has committed himself to the club until 2014.
"We are extremely happy Nick has signed his new deal," Powell told the club website.
"My staff and goalkeeping coach Ben Roberts have been delighted by his development in the short time he has been here and we look forward to him making further progress.
"He's already a popular player within the squad and is clearly benefiting from the day-to-day training."
Pope has been on the Addicks' first-team bench twice this season in the FA Cup and has also had spells on loan with Harrow Borough and Welling United.
