Middlesbrough defender Ben Gibson has signed a new five-year contract with the Premier League newcomers.
The 23-year-old, who has made more than 100 appearances for the club, made his top-flight debut last weekend against Stoke.
Gibson told Middlesbrough's official website: "I'm over the moon. I just want to make sure the next five years are in the Premier League with this club.
"It's a dream come true for me really and it's amazing for me and my family.
"It's an exciting time, and we're all looking forward to Sunday's game at Sunderland and hopefully picking up our first Premier League win."

Middlesbrough hope to tie up a deal for Valencia striker Alvaro Negredo after jetting out to Spain for a pre-season training camp.
The Teessiders have been in talks over the 30-year-old former Manchester City frontman for some time as they look to secure an initial loan deal.
Press Association Sport understands those discussions will continue in Marbella, where Boro will play three games starting with Tuesday night's friendly against Real Betis.
Head coach Aitor Karanka has already boosted his squad for life in the Premier League with six new additions in the shape of Victor Valdes, Viktor Fischer, Bernardo Espinosa, Marten de Roon, Jordan McGhee and Antonio Barragan, and he is not about to stop there.
The club is edging towards an agreement on Negredo, while they are also close to landing both Borussia Dortmund defender Neven Subotic and Uruguayan midfielder Gaston Ramirez.
Middlesbrough's busy summer has continued with the acquisition of Valencia defender Antonio Barragan on a three-year deal.
The 29-year-old right-back, who spent time with Liverpool as a teenager, is the sixth player to move to the north east in this window as Aitor Karanka shapes his squad ahead of their return to the Premier League.
Barragan has joined Victor Valdes, Viktor Fischer, Bernardo Espinosa, Marten de Roon and Jordan McGhee in Karanka's ranks and Boro hope his old Valencia team-mate Alvaro Negredo can follow too, with the clubs working on an initial loan deal.
Barragan left Liverpool in 2006 and played for Deportivo and Real Valladolid prior to joining Los Che, whom he made over a century of appearances for.
Manager Karanka signalled his pleasure at the latest capture:
I am really pleased he has signed. He is a player we know a lot about and he is a good addition to the squad. He is a good lad, and he has played a lot of games for Valencia.
He knows this country as well because he was at Liverpool as a young player. He is a good signing for us.

Tomas Kalas has admitted he would have to think seriously about a permanent switch to Middlesbrough if he was offered the chance to play for the club in the Barclays Premier League.
The 23-year-old Czech Republic international has spent the last 16 months on loan at the Riverside Stadium from Chelsea, where he signed a new three-year deal last summer.
However, the defender has made only two starts for the Blues since arriving from Sigma Olomouc in January 2011, compared with the 47 appearances he has made for Boro.
Kalas told the Evening Gazette: "I don't know how many games I've played since I came - probably around 40, which is not bad in one and a half years.
"That's why I came here, to play games and hopefully I'll keep playing next season - maybe here.
"If I could get the deal [to move to Boro permanently], I would really think about it. Yes, why not?"
TEAM NEWS: Dimi, Nsue, Ayala, Gibson, Friend Clayton, Leadbitter, Stuani, Ramirez, Adomah, Nugent.
Subs: Agazzi, Forshaw, Kalas, Downing, De Sart, Rhodes, De Laet.
Jordan Rhodes' stoppage-time winner gave Sky Bet Championship leaders Middlesbrough their sixth straight victory as they beat already-relegated Bolton 2-1 at the Macron Stadium.
Boro were trailing to the club propping up the division when Josh Vela scored but after Rhodes levelled in the 73rd minute, Boro mustered another late winner for the second time in five days, this time through their £9million striker.
Middlesbrough head coach Aitor Karanka looks to be heading for the exit after a failed attempt to smooth over a bust-up.
Press Association Sport understands the Spaniard reported for duty on Saturday morning ready to take training ahead of Sunday's Sky Bet Championship trip to Charlton, a day after walking out following a stormy meeting with his players.
Sources close to Karanka, who has previously found himself at odds with former assistant Craig Hignett and midfielder Albert Adomah during his 28-month reign, claim he arrived ready to apologise for his part in the disagreement and smooth things over.
However, he did not lead training and the club later released a statement confirming he will not be in charge of the team at the Valley.
