Wolves striker Kevin Doyle has signed a new contract that will keep him at the club until June 2015.
The Republic of Ireland international, 28, who has scored one goal in six games this season, had two years remaining on his previous deal.
Boss Mick McCarthy told the club's website: "It's great news Kevin has signed the new contract and his future is now secured for another four years.
"He remains a big part of what we are trying to achieve here."
McCarthy added: "He has been a key player for us in maintaining our Premier League status over the last two seasons when he has made a major contribution.
"From day one when he arrived he settled at the club and has been the consummate professional in the way he plays and also conducts himself off the pitch. We are delighted that he has agreed to extend his stay."
The club's joint record signing, who has scored 18 goals in 74 appearances since joining from Reading in June 2009, revealed he had agreed in principle to sign a new deal on the first day of pre-season.
"I'm delighted to have signed the new contract," he told www.wolves.co.uk. "It's something we've talked about for a while and to be honest it's been agreed for a while between myself and the manager and it was just a case of everything getting it all sorted.
"I don't really think there was anything in the speculation this summer.
"I'd actually spoken to the gaffer on the very first day of pre-season when we talked about this contract and I was keen to get it done.
"I am very happy here and am just looking forward to carrying on with the season.
"From the day I arrived I have settled at Wolves really well and everything has felt right.
"When you look around at what is being done with the stadium and the plans for the training ground you can see a long term plan in place which is exciting to be part of.
"There is a real feeling that the club is going places and I'm looking forward to being a part of it."
