Source: Jets trade for WR Marshall

— -- The Chicago Bears have agreed to trade wide receiver Brandon Marshall to the New York Jets, a source told ESPN NFL Insider Adam Schefter.

The trade, which cannot become official until free agency opens Tuesday at 4 p.m. ET, will also rely on Marshall passing a physical. The Jets are sending a fifth-round pick to the Bears in return, according to a source.

A nine-year veteran and five-time Pro Bowler, Marshall fought through nagging leg injuries most of last season and finished the year on the injured reserve due to fractured ribs and a punctured lung. He produced just 721 yards receiving. Prior to last season, Marshall racked up 1,000 yards receiving in seven consecutive seasons.

While Marshall's ability has never been questioned, he has often been a distraction.

Last season, Marshall was part of a postgame locker room rant after a loss to the Miami Dolphins, and he challenged a Detroit Lions fan to a boxing match on Twitter. In addition, he had weekly television duties as an analyst on Showtime's "Inside the NFL."

A mental health spokesman, the 30-year-old Marshall has seemed to put his past off-the-field issues in the rearview mirror. The mercurial receiver will join a Jets team that figures to rely on young quarterback Geno Smith and currently has receivers Percy Harvin and Eric Decker under contract, though Harvin is likely to be released by the team.

Jets first-year head coach Todd Bowles was a key voice in making the trade. He was a member of the Dolphins' coaching staff in 2010 and 2011, Marshall's two-year run with the team. The Jets' new director of college scouting, Rex Hogan, was a longtime Bears scout, so he, too, has familiarity with Marshall.

In a span of 12 months, the Jets have remade their once-woeful receiving corps. Their starters will be Marshall and Decker, whom they signed last year to a five-year, $36.25 million contract in free agency.

The move is the first major splash made by Chicago's new leadership regime. Coach John Fox and general manager Ryan Pace were hired by the Bears this offseason to succeed Marc Trestman and Phil Emery, respectively.

Marshall's wife Michi took to Instagram to issue a thank you to the city of Chicago.

While the Bears have elected to move Marshall, the team plans to re-sign backup quarterback Jimmy Clausen, a source told Schefter. The decision to re-sign Clausen comes at a time where the new Bears brass has remained noncommittal about the future of incumbent starter Jay Cutler, who is in the midst of a seven-year, $126.7 million deal. If Cutler is still on the Bears' roster on March 12, $10 million of his 2016 salary becomes guaranteed.
