Charlton defender Michael Morrison has put pen to paper on a new deal which will keep him at the Valley until summer 2016.
The 26-year-old has made 146 appearances for the Addicks since joining from Sheffield Wednesday in 2011.
Morrison's contract was due to expire in July, but the centre-back will now remain at the club for a further two years.
He told the club's official website: "I'm really pleased to get it over the line.
"It's taken a long time but the club have always said they want to keep me and I really wanted to stay and go into a new era which I think is going to be successful.
"We've kept enough of the core to build from and we've got some exciting players coming in who I hope can hit the ground running and take us up the league."
