Tom Pelissero and Mike Garafolo of NFL Network provided the news Saturday. NFL Network's Ian Rapoport reported Seattle is "a preferred location" for Clowney and noted he'd sign the one-year contract tender associated with the franchise tag if traded to the Hawks.
Fox Sports' Jay Glazer added the two sides "have agreed to trade parameters" that are "contingent upon Clowney and other players involved passing physicals."
The 26-year-old University of South Carolina product has remained away from the Texans, who placed the franchise tag on him in March, throughout training camp and the preseason. A trade can't happen until he signs the one-year tender.
The Texans had offered Clowney and a first-round pick to the Dolphins in exchange for offensive tackle Laremy Tunsil, per Barry Jackson of the Miami Herald.
Clowney, the first overall pick in the 2014 draft, overcame injury issues early in his career to become a force off the edge. He's tallied 29.0 sacks in 58 games over the last four years, including 18.5 sacks since the start of the 2017 campaign.
Texans head coach Bill O'Brien said Friday the pass-rusher's continued absence as the preseason came to a close was "a matter of difference of opinion on value."
"The ball is in his court," O'Brien told reporters.
There has been no indication of whether Clowney would return to the Texans under the tag if no trade is made.
In Seattle, the three-time Pro Bowl selection would likely shift back to defensive end, the position he played with the Gamecocks, and be expected to bolster a pass rush that finished tied for 11th in sacks last year.
