Dion Jordan will be suspended for the 2015 season for another substance abuse policy violation. Jordan didn't fail a drug test, but one of his test samples was diluted, which counts as a strike.

Jordan was the third overall pick in the 2013 NFL Draft by the Miami Dolphins.

Jordan was suspended for the first four games of the 2014 season and violated the policy again on Sept. 19.

Greg Jennings has signed with the Miami Dolphins.

The Dolphins had a need for a veteran receiver.

Jennings' production has dipped since leaving the Green Bay Packers for the Minnesota Vikings in free agency.

The Miami Dolphins could again invest a first round pick in their offensive lineman.

La'el Collins of LSU is among the frontrunners for the Dolphins with the 14th overall pick.

Last season, the Dolphins picked Ja'Wuan James.

Mike Pouncey and the Miami Dolphins have agreed upon a five-year, $50 million contract extension.

Pouncey will receive upward of $20 million in guarantees. The new contract makes Pouncey the NFL's richest center.

The 2011 first-round pick was set to play next season under the $7.4 million, fifth-year option attached to his rookie contract. 

The Miami Dolphins are close to agreement on a multi-year extension with Mike Pouncey.

Pouncey's deal will be worth approximately $40 million.

Pouncey is one of the NFL's best centers.

Wes Welker is visiting the Miami Dolphins to discuss a deal.

Welker began his career with the Dolphins in 2004. However, Miami traded Welker to the AFC East rival New England Patriots in 2007.

Welker recorded 49 receptions for just 464 yards and two touchdowns last season with the Denver Broncos as he battled concussions. 

Welker hasn't garnered much interest from Denver.

Michael Crabtree will visit the Oakland Raiders next week as he continues his free agency process.

Crabtree has also visited the Miami Dolphins.

Crabtree has found his market to be soft this offseason. The San Francisco 49ers have interest in re-signing Crabtree.

The Miami Dolphins have signed Josh Freeman.

Freeman was a starter for several seasons with the Tampa Bay Buccaneers, but has since bounced around with the Minnesota Vikings and New York Giants.

Freeman was ranked 86th on the NFL's Top 100 Players of 2011.
