Denny Hamlin has signed a contract extension with Joe Gibbs Racing.

Hamlin officially announced the signing on Twitter.

"Yeah, we announced on my Twitter just a few minutes ago that (I) signed an extension with Joe Gibbs Racing," he said after posting it. "Just proud of all the effort everyone put into getting me signed. Really for myself, it's great to know where you're going to be for the foreseeable future. Know that if I'm going to win a championship, I know it's going to be with the team that I'm with. Proud to be with FedEx. Proud to be with Joe Gibbs Racing."

Team owner Joe Gibbs did not reveal terms of the contract.

"We pride ourselves on long-term deals," he said. "Denny's done a great job for us and he's done a great job for FedEx."

Hamlin, 31, made his debut with JGR at Kansas Speedway in 2004. After moving to the Sprint Cup Series full time the following season, the Chesterfield, Va.-native qualified for the Chase for the Sprint Cup for six consecutive seasons with crew chief Mike Ford calling the shots.

Although Hamlin and Ford parted ways after last year, defending championship crew chief Darian Grubb has taken over the leadership of the No. 11 JGR team. Hamlin is currently eighth in the points standings.

In 239 career Cup starts, Hamlin has amassed 19 wins, 73 top-fives and 119 top-10 finishes.

Although there are rumors of Matt Kenseth joining JGR, Gibbs opted not to speculate. When asked whether an announcement could come in mid-August, he simply chuckled.

"We're still trying to re-sign Joey (Logano)," Gibbs said. "We're working real hard right now on extending him and his relationship with us. We've had a great relationship, signed him when he was 15. We've got a lot invested in Joey. I think right now he's stepping up, and we want him to be with us.
