IRVING, Texas — Two people with knowledge of the situation said Dallas Cowboys linebacker Rolando McClain has been suspended for the first 10 games next season for his second violation of the NFL’s substance-abuse policy in as many years.

McClain was suspended the first four games last season. He signed a second straight one-year deal with the Cowboys in March, this one worth $5 million.

The people, speaking to The Associated Press on condition of anonymity Thursday because the NFL hasn’t announced the suspensions, also said defensive end DeMarcus Lawrence’s appeal was denied. Lawrence will be suspended the first four game for a substance-abuse violation.

JOHNNY MANZIEL has been suspended for the first four games of next season for violating the NFL’s substance-abuse policy, and the free-agent quarterback could face further discipline over his domestic violence case if he signs with a team.

The suspension isn’t related to the league’s domestic violence policy, but Manziel would be subject to standards that were toughened two years ago if he signs with another team.

The 23-year-old Manziel, released by Cleveland in March, faces a misdemeanor assault charge in Dallas involving his former girlfriend, Colleen Crowley. As Manziel’s domestic case has played out, he has been photographed partying from Hollywood to Las Vegas to New York in recent months.

JETS: Sheldon Richardson was suspended by the NFL for the first game of the 2016 regular season for violating the league’s personal conduct policy.

Richardson will be eligible to return to the Jets’ active roster on Sept. 12 following the team’s Sept. 11 opener against Cincinnati. But he can participate in all preseason practices and games.

He pleaded guilty in January to resisting arrest after police clocked him driving at speeds as high as 143 mph in Missouri last July. Resisting arrest is listed by the NFL as a violation of the personal conduct policy.

GIANTS: Almost a year after mangling his right hand in a fireworks accident, defensive end Jason Pierre-Paul made a public service announcement about keeping children away from fireworks, and warning everyone to handle the pyrotechnic devices with care.

The announcement was unveiled at a fireworks safety event in Washington by U.S. Consumer Product Safety Commission Chairman Elliot F. Kaye.

Pierre-Paul lost an index finger and part of his thumb, and was required to have reconstructive surgery to save his middle finger when a device exploded in his hand on July 4.
