Couppacup has been fired for travelling to the Seahawks.
Shortly after signing the Seahawks contract, Kupp joined social media and expressed his excitement through X's post.
“Washington is back in my heart. Let's go!!!” his post says.
Kupp, 31, originally from Yakima, Washington, was a standout at Eastern Washington University before being drafted by the Rams in the 2016 NFL Draft.
Before joining the Seahawks, Kupp spent all his eight years with the Rams and was named Player of the Year, winning the Super Bowl in 2021.
All-Pro Wideout signed a three-year, $45 million contract with Seahawks on Friday, per multiple reports.
Kupp's contract with Seattle is a number of changes to the team's wide receiver.
The Seahawks traded DK Metcalf for the Steelers on Sunday and released the Tyler Rocket last week.
In addition to Kupp's deal, the Seahawks acquired quarterback Sam Darnold in free agency and signed a three-year, $100 million contract at the age of 27.
