The frenetic pace of maneuvering to sign or release players this week caught up to the Denver Broncos.
Broncos president John Elway called on defensive end Elvis Dumervil to accept a salary reduction or face the possibility of being released. Dumervil agreed to the reduction, but was shockingly released when paperwork for the adjusted contract wasn't filed by 3:59 p.m. ET Friday.
The Denver Post reported Dumervil informed the Broncos he would lower his 2013 salary to $8 million. Under the terms of his previous six-year, $61.5 million deal signed in 2010, Dumervil was set to receive a base of $12 million for this season.
But the Broncos did not receive the signed documentation until several minutes after 4 p.m. ET, when his contract would have become fully guaranteed, the Post reported.
If the Broncos attempt to re-sign him, they'll have to take the cap penalty for releasing him into account as well as any new figure that would arise from a new deal.
---Tight end Tony Gonzalez made his return for the 2013 season official by signing a two-year contract with the Atlanta Falcons.
The two-year deal is worth $14 million, according to NFL.com. He is guaranteed to receive $7 million in 2013, but there is no indication he will return for the 2014 season. The second year of the deal was included for bookkeeping purposes, according to the report.
---Quarterback Kevin Kolb was released by the Arizona Cardinals in a expected move that saved the team $7.5 million in salary cap space.
The Cardinals signed defensive end Matt Shaughnessy, who played his first four seasons with the Oakland Raiders to a one-year deal, Pro Football Talk reported.
They also signed cornerback Antoine Cason to a one-year contract, the Arizona Republic reported. He started all 16 games for the San Diego Chargers last season.
---The Philadelphia Eagles announced they have acquired receiver Arrelious Benn along with a 2013 seventh-round draft pick from the Tampa Buccaneers in exchange for a sixth-round pick this year and a conditional draft pick in 2014.
Benn played in eight games for the Bucs in 2013, but he had only four catches for 26 yards.
---The Miami Dolphins signed tight end Dustin Deller to a one-year, $4.25 million contract, according to multiple reports.
The Dolphins also signed wide receiver Brandon Gibson to a three-year deal, according to the St. Louis Post-Dispatch.
--Free agent running back Danny Woodhead, who played last season for the New England Patriots, signed a two-year contract with the San Diego Chargers.
Woodhead's move comes on the heels of slot receiver Wes Welker also leaving the Patriots and signing with the Broncos.
The Chargers also signed running back Ronnie Brown to a one-year deal.
--- Cornerback Kyle Arrington re-signed with the Patriots, agreeing to a four-year deal.
The Patriots also signed wide receiver Donald Jones, a onetime starter for the Buffalo Bills.
--- Dwight Freeney was one of three former Pro Bowl defensive players and a restricted free-agent wide receiver scheduled to gain an audience with Patriots coach Bill Belichick.
Defensive end John Abraham and strong safety Adrian Wilson were also scheduled to be in Foxborough along with receiver Emmanuel Sanders.
The three defensive players were released in recent weeks.
---Safety Louis Delmas reach an agreement to stay with the Detroit Lions. He will sign a two-year, $9.465 million contract, according to multiple reports.
---Seventh-year linebacker Nick Roach signed with the Oakland Raiders and is expected to be the starting middle linebacker in 2013.
Roach, primarily a strong-side linebacker for the Chicago Bears over the past five seasons, filled in for injured middle linebacker Brian Urlacher in 2012, starting 14 games.
