Cowboys’ Rolando McClain gets 10-game suspension

Former Raiders linebacker Rolando McClain was suspended 10 games Thursday for his second violation of the NFL’s substance-abuse policy in two years, leaving the Dallas defense without three starters to open the season.

McClain, who was suspended the first four games last year, now is sidelined with defensive end DeMarcus Lawrence, who was suspended four games on a substance-abuse violation after an appeal was denied.

Dallas has had four defenders with season-opening suspensions over NFL policies the past two seasons.

The suspension announced Thursday is not related to the NFL’s domestic-violence policy, but the free-agent quarterback would be subject to it if he signs with a team.

Briefly: NFL Commissioner Roger Goodell earned just more than $31 million for 2015, the league said, a decrease from his 2014 salary of approximately $34 million. ...

Jets defensive lineman Sheldon Richardson was suspended for the first game of the 2016 regular season for violating the league’s personal-conduct policy.
