CLEVELAND

Josh Gordon’s curious and complicated career has taken a new turn.

He’s getting yet another chance.

The talented but troubled wide receiver has been reinstated on a conditional basis by NFL Commissioner Roger Goodell, who met face to face with Gordon last week and said he believes the 25-year-old can “make the right choices” going forward.

Gordon has been banned since February 2015 for multiple violations of the league’s drug policies. He will be suspended for the first four games of the 2016- 17 season, but he’s allowed to join the team in its upcoming training camp and can participate in meetings and conditioning work.

The league said once Gordon meets clinical requirements, he can take part in preseason activities, including practices and games. The Browns have their first practice of training camp Friday.

It’s a fresh start for Gordon, who emerged as one of the league’s rising stars in 2013 before several missteps led to his banishment.

Gordon expressed his gratitude in a message on Twitter.

“I’m blessed and grateful to be granted this opportunity,” he wrote. “I can’t wait to get back out there and play the game I love in front of the great fans of Cleveland.

“I want to thank the NFLPA, Commissioner Goodell, the Haslam family and Browns organization, my agent Drew Rosenhaus, as well as my mentors for their continuous support along the way.

“I’ve heard only good things from my teammates about the positive direction the organization is heading and I want to do everything I can to be there to help further that process not only for the team but to better myself as well.”

Dockett retires

TEMPE, Ariz. (AP) — Darnell Dockett, the big, boisterous defensive lineman who overcame a rough childhood to thrive in the NFL, said goodbye to the league the way he wanted — as an Arizona Cardinal.

The 35-year-old player signed a one-day contract with the team on Monday and announced his retirement at a news conference.

Dockett, never at a loss for words, said he’s “very thankful” and “beat the odds” to make it in the NFL.

He played 10 seasons with Arizona after the Cardinals selected him in the third round of the draft out of Florida State.

Aldon Smith

ALAMEDA, Calif. (AP) — The NFL is investigating whether a video linked to an account from suspended Oakland

Raiders linebacker Aldon Smith shows him using illegal drugs.

A video on a periscope account that has shown Smith in the past features an unidentified man off camera discussing a rolled cigarette with an unidentified woman. It’s not clear what’s in the cigarette and who the man is. Smith sent out a tweet Monday after CSNBayArea.com reported on the video saying “Good try, not me.”

NFL spokesman Brian McCarthy says the league is investigating.

Smith is serving a one-year suspension for violating the league’s substance abuse policy that ends Nov. 17. He can apply for reinstatement in September. He gets regularly drug tested while on suspension.

Jordy Nelson

GREEN BAY, Wis. (AP) — Receiver Jordy Nelson won’t practice when the Green Bay Packers begin training camp on Tuesday.

Nelson was one of six Packers placed on the physically unable to perform list on Monday. Nelson is coming back from a torn right ACL injury that kept him out for the 2015 season.

The Packers have said that they might be cautious with Nelson as he comes back from injury. The Packers also have five preseason games this year since they play in the Hall of Fame game on Aug. 7.

Other Packers starting on the PUP list include linebacker Sam Barrington and tight end Jared Cook; receiver Ty Montgomery (ankle); guard T.J. Lang (shoulder) and center Corey Linsley.

Concussion protocol

NEW YORK (AP) — The NFL and the players association have announced a new policy regarding game-day concussion protocol and discipline for clubs that violate the procedure.

Under the new policy jointly announced Monday, the NFL and NFLPA “will follow a strict and fair process to investigate incidents and determine appropriate discipline, including club fines and possible forfeiture of draft picks.”

The league and the players union will each designate a representative to monitor the implementation of the protocol and investigate potential violations. The probe won’t reach medical conclusions; it will only determine if the protocol was followed. An arbitrator will handle cases where the league and union disagree and report to the commissioner.

Commissioner Roger Goodell retains sole discretion in determining penalties for violations of the game-day concussion protocol.

A first breach will require club employees or medical team members involved to attend remedial education and/or result in a maximum $150,000 fine against the team. Clubs will be fined a minimum $100,000 for subsequent violations.

There are additional penalties if the violation involves aggravating circumstances, and the commissioner may impose more severe financial penalties and require clubs to forfeit draft picks if it’s determined that a club’s medical team ignored protocol for competitive reasons.
