Sheffield United defender John Egan has signed a new four-year contract.
The Republic of Ireland international centre-back, who made 36 Premier League appearances last season, has committed his future to the Blades until the summer of 2024.
Egan, 27, told the club's official website: "The last two years have probably been the most successful of my career and to get the chance to sign a new contract here is brilliant for me and I’m really looking forward to the future. I need to thank everyone involved.
"I’ve loved my time here. We won promotion in the first year and had a real good first season back in the Premier League, so now it is about building on that and improving in the future."
Blades boss Chris Wilder signed Egan from Brentford in 2018.
Wilder said: "It’s a reward for the influence John has on the team and at the football club. He’s been part and parcel of our climb over the last two years and he’s taken his game to the next level.
"John has been outstanding and knowing the boy as we do, we know John is not a comfortable footballer, he wants to establish himself and continue to improve at the highest level."
Egan is one of a strong Ireland contingent at Sheffield United that also includes FAI Player of the Year David McGoldrick, left-back Enda Stevens and winger Callum Robinson, who spent last season on loan at Championship runners-up West Brom.
Ireland U21 Stephen Mallon is also on loan at Derry City from the Blades.
Meanwhile, Lewis Dunk has signed a new contract at Brighton which will keep him at the club for the next five years.
The 28-year-old England defender has been linked with a move away from the AMEX Stadium this summer, but the Seagulls confirmed on Friday that he has agreed new terms on the south coast.
