George Honeyman has signed a two year deal with the Black Cats.
The 22-year-old's contract was due to expire in the summer, but he looked set to secure an automatic extension as he broke into the first team set-up at the end of the season.
He was a matter of minutes away from doing so but his season was ended when centre-half Lamine Kone fell on him in training.
The Black Cats have nevertheless moved quickly to secure his future and have awarded his strong end of season form with a two year contract.
Honeyman was one of eight players whose contracts expire this summer, the midfielder becoming the first to commit to the club. The Black Cats remain in negotiations with a number of those players with a retained list expected in the coming weeks. Key decisions were made before David Moyes' departure as to who the club would keep on, with the former boss stressing that it would be important to retain the services of one or two players 'who knew the club', with a high turnover of players expected this summer.
Honeyman made six first team appearances last season, all in 2017, and is set to be a prominent squad member as the club adjust to life in the Championship.
He said: “I’m delighted it has all been finalised and now I’m looking forward to working hard and spending the next couple of years at Sunderland,
“It means everything to me and my family to play football for our first-team. I have loved every second of my time at the club ever since they were taking me in four times a week when I was 11.
“I owe them a lot and wouldn’t have achieved this without them.
“I want to be a regular in the team and help achieve promotion and I truly believe next season we can achieve both of those things.”
