West Brom's longest serving player, midfielder James Morrison, has signed a new four-year contract.
The Scottish international has put pen to paper on a deal which will keep him at The Hawthorns until the summer of 2016.
Morrison, who joined the Baggies from Middlesbrough five years ago, has played a major role in establishing the club in the Barclays Premier League.
Morrison had two years remaining on his previous deal.
West Brom head coach Steve Clarke said: "After strengthening the squad during the transfer window, it's equally important to hold on to your best players.
"I'm delighted James has signed a new deal and the new contract is fair reward for his hard work and efforts.
"He's been at Albion for a number of years now and has always been one of the key players.
"This is a good message to send to the rest of the squad, that if you do well and keep improving you will be rewarded.
"It's also a big coup for the club because I'm sure that if James was on the market, there'd be a few clubs interested in him."
The club's sporting and technical director, Dan Ashworth, added: "James has been one of our most effective players in the Premier League over the last couple of seasons and fully deserves his improved deal.
"The fact we've got a player of James' calibre to sign a longer contract is a sign that the club is moving in the right direction."
Morrison helped West Brom win the Championship title in his first season at the Hawthorns.
Clarke revealed Albion are also still in talks with central defender Jonas Olsson over a new contract.
The Sweden international has entered the final year of his current deal with his future still unresolved.
Clarke said: "The club are still talking to Jonas. The chairman (Jeremy Peace) and Dan Ashworth (sporting and technical director) are in negotiations.
"Jonas respects the fact we are keeping him for the last year of his contract, and we respect the fact he's in the last year of his contract.
"If we can find a solution, that's what we'll do, and that's what we're working to do."
