Ciaran Clark has followed the lead of fellow central defender Nathan Baker by signing a new long-term contract with Aston Villa.
Baker put pen to paper on a deal until 2019 last week and Clark has agreed fresh terms to cover five more years.
Now 25, Clark is a product of Villa's youth system and has been a regular first-team fixture in recent seasons.
The Republic of Ireland international started 22 Premier League matches last term before suffering a season-ending knee injury at Tottenham in April.
With Ron Vlaar's Villa contract having expired, Clark will now seek to play a leading role under Tim Sherwood.
Villa's manager said: "It's great news. You know what you're going to get from Ciaran - he gives everything for the cause and that's all you can ask for as a manager.
"He was unfortunate with injuries last season but he looks sharp now and we want to keep him fit. We're pleased to have him here for a longer time."
Clark added: "I'm absolutely thrilled to sign a new contract.
"Everyone is looking forward to the new season and I'm delighted to be going into the opening game on Saturday knowing my long-term future has been sorted."
Villa open the campaign against Premier League new boys Bournemouth on Saturday.
