The new league year and the official start of NFL free agency doesn't begin until 4 p.m. ET on Wednesday, but several teams around the league have already made unofficial moves to help improve their rosters.
No team has been more active than the Philadelphia Eagles, who traded star running back DeMarco Murray to the Tennessee Titans, as well as cornerback Byron Maxwell and linebacker Kiko Alonso to the Miami Dolphins.
Check out the latest NFL news and rumors below.
• The Carolina Panthers cut defensive end Charles Johnson earlier this off-season, but he's returning to Carolina. Joe Person of the Charlotte Observer reports Johnson is taking a one-year, $3 million deal with the Panthers, turning down deals worth twice that amount.
• The New York Giants landed cornerback Janoris Jenkins. Schefter reports that the five-year deal is worth $62.5 million.
• The Minnesota Vikings announced that they cut wide receiver Mike Wallace. The move saves the team $11.5 million in cap space.
