Thomas has been one of Seattle's most consistent performers.
The post was a surprising conclusion to a long off-season of drama centred on whether Thomas would play out the final season of his contract, receive the extension he hoped for, or possibly be traded.
Thomas confirmed his return in an Instagram post, but it appears there is still tension with the Seahawks, as he wrote: "The disrespect has been well-noted and will not be forgotten". Thompson missed the final preseason game with a shoulder stringer and rib injury suffered a week earlier, but coach Pete Carroll had said Monday that Thompson was in line to start the opener.
Thomas stood to begin losing game checks of $500,000 per weekend if he does not report in time to be on the active roster for the opening game, that is, 24 hours before Sunday's 1:25 p.m.

The Australian is ranked No 55 in the world and for his heroics will be rewarded by a quarters clash against Novak Djokovic . The Spaniard will be at that stage for the second time at the US Open, five years after her other run to that round.
The Seahawks insist they are not willing to give away Thomas, who has held out of training camp because of his contract, a source told Schefter on Saturday. Sherman was released by Seattle in the off-season and signed with San Francisco.
The Seahawks reportedly called the Cowboys on draft night, asking for the 50th pick alone in exchange for Thomas, a six-time Pro Bowler.
Seattle had been thought wanting at least a second-round pick all along with it thought Dallas had not offered more than a third.
Precedent from safety Kam Chancellor's holdout into the 2015 regular season suggested the Seahawks are going to collect from Thomas this time, too.
At this point the relationship between Thomas and the only National Football League team he's known, the Seahawks, Schneider and coach Pete Carroll who drafted him in the first round in 2010, seems irreparable.
