According to Ian Rapoport of NFL Network, the 28-year-old is "firmly in [the Seahawks'] plans for the 2018 season."
Rapoport also noted the Seahawks are looking to reach a "long-term" agreement with Thomas.
Thomas has a base salary of $8.5 million in 2018.
For the sixth time in his career, Thomas earned a Pro Bowl nod. He recorded 88 tackles, two interceptions, one forced fumble, one touchdown and seven passes defended.
The eight-year veteran missed two games last season due to a hamstring injury and also later dealt with a heel injury. He did not miss a game during the first six years of his career, however.
Thomas made headlines last season when he told Dallas Cowboys coach Jason Garrett, "If y’all have the chance, come get me." Well, it appears Garrett won't have an opportunity to acquire the lifelong Cowboys fan.
It's important to note that Thomas made it clear at the Pro Bowl he would not return to the Seahawks without receiving security, courtesy of NFL Network's Jane Slater:
Thomas' value to Seattle may be higher than ever due to the current question marks surrounding the Legion of Boom. Both Kam Chancellor (neck) and Richard Sherman (Achilles) suffered major injuries last season. Seahawks coach Pete Carroll is on record, per Bob Condotta of the Seattle Times, saying that he believes Chancellor will have a "hard time playing football again."
Seattle has reportedly decided that keeping Thomas is in the best interest of the team. What remains unclear is whether or not the two sides will be able to work out an extension that gives both sides what they want.
