The Buffalo Bills and All-Pro wide receiver Stefon Diggs have agreed to a four-year, $104 million contract extension, according to ESPN. The deal includes $70 million guaranteed and now ties the Maryland product to Orchard Park for the next six seasons.

At the NFL Owner's meetings late last month, general manager Brandon Beane acknowledged, via WKBW, that he has had "open dialogue" with Diggs' agent since the season concluded but would not go any further into the state of negotiations at that time. He closed by saying:

"I have a great relationship with Stef and he knows if there is ever a concern to call me directly and I will do the same."  

Diggs, who was the No. 146 overall draft pick in the 2015 NFL Draft, was acquired from Minnesota in March of 2020. Buffalo surrendered a first round pick, fourth round pick, fifth round and sixth round pick in exchange for the wide receiver and a seventh-round choice.

Over the past two seasons, Diggs has found individual and team success. He was named to the NFL Pro Bowl both seasons and has amassed 230 receptions for 2,760 yards, and 18 touchdowns. For the first time in his career, he was named first-team All-Pro in 2020. The Bills advanced to the Divisional Round of the NFL Playoffs or better in each of those two seasons; both ending with a loss to Kansas City. 

Diggs had two years remaining on his current contract, which was slated to carry roughly an $18 million salary cap hit in each season. The news comes during the same off-season in which Tyreek Hill ($72.2 million guaranteed) and Davante Adams ($65 million guaranteed) received lucrative contract extensions of their own. 

It has been a busy off-season for Buffalo bringing in edge rusher Von Miller, O.J. Howard, Rodger Saffold and others. In addition to Diggs, the team has Jamison Crowder, Gabriel Davis and others at the wide receiver position.
