Miami Dolphins defensive end Dion Jordan will sit out the 2015 season as the result of an NFL suspension for a positive drug test.

Jordan, the No. 3 overall pick in the 2013 NFL Draft, will not appeal the ban, which came from a diluted test sample.

Jordan also was suspended for the first four games without pay in 2014 after violating the NFL’s substance abuse policy and later given an additional four-game suspension for violating the policy.

ESPN reported that the suspension puts an end to possible trade discussions with the Philadelphia Eagles in February regarding Jordan. The 25-year-old played at Oregon when Eagles coach Chip Kelly was with the Ducks.

In two NFL seasons, Jordan has fallen short of expectations with just three sacks and 46 tackles in 26 regular-season games.

–Three days before the 2015 NFL Draft, Missouri defensive end Shane Ray was ticketed for marijuana possession, and the citation could wind up costing him millions.

Ray reportedly also failed a drug test early in his time at Missouri. The latest incident automatically puts Ray in the first phase of the NFL’s substance abuse program, ESPN reported Tuesday, meaning he will not face league disciplinary action but will be subjected to random drug testing.

Ray, a projected top-20 pick by NFLDraftScout.com, apologized in a statement released Monday night after being cited for possession of marijuana.

–Offensive tackle La’el Collins, a possible first-round pick in Thursday’s NFL Draft, is being sought by police for questioning in connection with a murder investigation, multiple media outlets reported Tuesday.

Collins, who played college football at LSU, is not a suspect in the case, but police are trying to get more information about the death of a 29-year-old pregnant woman who was shot and killed on Friday in Baton Rouge, La.

–The Cincinnati Bengals picked up the fifth-year options on cornerback Dre Kirkpatrick, a first-round pick in 2012, and guard Kevin Zeitler. CBS Sports first reported Kirkpatrick’s option was picked up after some rumblings last week about a long-term deal. The one-year deal is expected to be worth $7.5 million.

–Outside linebacker Quanterus Smith was waived by the Denver Broncos. Smith appeared in 15 regular-season games for the Broncos during his first two NFL seasons.

–The New York Jets were hit with a $100,000 tampering fine from the NFL for owner Woody Johnson’s comments about cornerback Darrelle Revis, according to a report.

Revis, who became a free agent after spending last season with the Super Bowl champion New England Patriots, signed with the Jets last month.

The New York Daily News reported the fine but also indicated that the Jets would not lose any draft picks as part of the league’s discipline.

–Kansas City Chiefs president Mark Donovan signed a long-term contract extension with the team.

Donovan came to Kansas City in 2009 as chief operating officer and was elevated to team president in 2011. The Chiefs have a 43-53 record and reached the playoffs twice since he arrived six years ago.

–Minnesota Vikings general manager Rick Spielman did his best to quiet speculation surrounding a possible trade of running back Adrian Peterson.

“We can just end the Adrian Peterson stuff,” Spielman said Tuesday. “Our position has not changed. … We have no interest in trading Adrian Peterson.”

–The Houston Texans reached a contract agreement with restricted free agent running back Chris Polk, according to multiple reports. Polk was on the market after the Eagles rescinded their free agent offer.

–The Buffalo Bills announced they have exercise the fifth-year option on cornerback Stephon Gilmore’s contract, worth $11 million. Gilmore, 24, has started 39 of 41 career games since being selected with the 10th overall pick in the 2012 NFL Draft.

–Commissioner Roger Goodell informed team owners that the NFL is giving up the tax-exempt, not-for-profit status the league was granted in 1942.

Going forward, the league will operate as a taxable entity just as each team has done through the years. The NFL had come under criticism from Congress and others in recent years because of the federal tax exemption.

–For the second time in five weeks, Goodell said he expects the Deflategate report from investigator Ted Wells to be released “soon.”

–Running back Maurice Jones-Drew was honored by the Jacksonville Jaguars with a retirement ceremony.

Jones-Drew, a second-round pick of the Jaguars in 2006, is retiring having spent the first eight of nine NFL seasons in Jacksonville. He played sparingly for the Oakland Raiders in 2014.

–Punter Chris Jones agreed to a contract extension with the Dallas Cowboys. The deal keeps Jones in Dallas through the 2017 season.
