Mark Hughes has signed a new contract as Stoke manager which ties him to the club until 2019.
Stoke announced on Friday evening they had initially mis-reported the terms of the deal, having said the contract ran until 2018.
"We apologise for our earlier blunder. Mark Hughes has agreed a new deal until 2019, NOT 2018 as we reported," the club said on Twitter.
"In other news, the media team will not be receiving a Christmas bonus this year ... Apologies once again!"
Hughes' previous deal was due to expire in 2016, but he revealed in January that he was in talks to extend his stay.
Hughes has been at Stoke since May 2013 and has guided them to 10th in the Barclays Premier League this season.
He told the club's official site: "I'm delighted to have signed a new contract. I think it's exciting times for Stoke City, everyone can see there's more progress to be made and we want to see how far we can take the club.
"I came here 18 or so months ago and it's gone as well as I could have hoped - we've certainly kept progressing which is vitally important from my point of view.
"This season has been more difficult than last season due to circumstances, like injuries to key players, but we've still been very competitive and I believe we can do even better next season with a little bit more investment. Let's see how far we can go."
Hughes, 51, guided the Potters to their first top-10 finish in the Barclays Premier League last season and could repeat the feat this year, although they have lost their last two games.
And the former Wales and Manchester City manager is hoping securing his future will help the club.
He added: "Continuity is a huge thing in football, certainly in the Premier League, and hopefully the fact I've signed a new contract will give continuity to the club and, more importantly, the players because it helps them when they work with someone for a prolonged spell."
Ex-Manchester United and Chelsea striker Hughes replaced Tony Pulis in 2013, having been sacked by QPR in November 2012, and has also managed Blackburn and Fulham.
Stoke go to Chelsea next on April 4 after the international break.
