More than 50 NFL free agents have signed deals with teams since the three-day negotiation period expired at 4 p.m. (ET) on Tuesday. (UPDATE at bottom of the post — 5:30 p.m. ET)

Among the most active teams were the Miami Dolphins, who signed former Pittsburgh Steelers wide receiver Mike Wallace and Baltimore Ravens linebacker Dannell Ellerbe, while re-signing wide receiver Brian Hartline. Wallace received a five-year, $65 million deal, while Ellerbe agreed to a five-year, $35 million contract. Hartline received a five-year, $30 million pact to stay in Miami.

The Dolphins lost running back Reggie Bush on Wednesday. The team's leading rusher in 2012, Bush agreed to an as-yet undisclosed deal with the Detroit Lions. Miami hasn't re-signed offensive tackle Jake Long, who remains one of the most sought after NFL free agents.

Linebacker Paul Kruger followed former teammate Ellerbe out of Baltimore, signing a five-year, $40 million deal with the Cleveland Browns. In all, the Super Bowl champion Ravens have lost Kruger, Ellerbe, the retired Ray Lewis and released safety Bernard Pollard from their championship defense. Baltimore safety Ed Reed had yet to sign a new contract. The Ravens also traded receiver Anquan Boldin to the San Francisco 49ers for a sixth-round pick in April's NFL Draft.

In other notable signings, former 49ers' safety Dashon Goldson agreed to a new contract with the Tampa Bay Buccaneers on Wednesday, and former Steelers' running back Rashard Mendenhall signed a one-year contract with the Arizona Cardinals. The New York Giants lost tight end Martellus Bennett to the Chicago Bears on Tuesday, but the Falcons and tight end Tony Gonzalez were working out a new deal that would keep the future Hall of Famer in Atlanta and away from retirement.

Notable players released during the free agent period and its interim were Steelers linebacker James Harrison, Buffalo Bills quarterback Ryan Fitzpatrick, Philadelphia Eagles cornerback Nnamdi Asomugha, Jacksonville Jaguars wide receiver Laurent Robinson, Steelers guard Willie Colon, Cardinals running back Beanie Wells, Washington Redskins cornerback DeAngelo Hall and Minnesota Vikings cornerback Antoine Winfield.

The Vikings also traded wide receiver Percy Harvin to the Seahawks. Harvin signed a six-year, $67 million pact with Seattle after the deal.

A slew of highly sought-after defensive ends, including Cliff Avril of the Lions, Dwight Freeney of the Indianapolis Colts and Osi Umenyiora of the Giants, had yet to agree to terms with a team. Baltimore's Reed, Eagles cornerback Dominique Rodgers-Cromartie and Patriots cornerback Aqib Talib were the best defensive backs still available.

Miami's Long, Patriots' receiver Wes Welker* and Green Bay Packers' wide receiver Greg Jennings were among the most coveted offensive players yet to sign new deals as of Wednesday afternoon.

*UPDATE: Welker reportedly agreed to terms with the Denver Broncos on a two-year, $12 million deal on Wednesday afternoon.
