Denver Broncos restricted free agent wide receiver Brandon Marshall has signed his one-year tender, ESPN's Adam Schefter reports.

Schefter adds that the move was done to facilitate trade talks between the Broncos and other teams. Marshall could not be part of any trade until he had signed his tender, which is worth $2.521 million dollars for the 2010 season.

The Broncos have reportedly been insisting on a first-round pick in exchange for Marshall, a two-time Pro Bowler the Broncos chose in the fourth-round of the 2006 NFL Draft. However, by tendering him at the less prohibitive "First Round" level, they were signaling to other NFL clubs that compensation was, at the very least, negotiable.

Marshall visited the Seattle Seahawks on the opening days of free agency, and the Seahawks remain the only team to openly express any interest in acquiring Marshall, who played for Seahawks offensive coordinator Jeremy Bates and quarterbacks coach Jedd Fisch in Denver in his first few seasons in the NFL.

The Seahawks have two picks (6 and 14) in the first-round of this year's draft, but are unlikely to part with either of them to acquire Marshall. The Seahawks still have a second-round draft choice, swapping picks with the San Diego Chargers in the trade for quarterback Charlie Whitehurst, with the Seahawks dropping twenty spots to the 60th pick in the draft.

Seahawks head coach Pete Carroll acknowledged at the league meetings in Orlando that Seahawks general manager John Schneider had spoken to the Broncos and Marshall, but characterized the talks as "preliminary".

Now that Marshall has signed the one-year tender, talks between the Broncos and Seahawks should heat up quickly.
