The NBA is recommending teams address fans or show videos expressing themes of unity before their first home games, while reminding them of the rule that players must stand for the national anthem.

A memo was sent to teams Friday, a day after Commissioner Adam Silver said he expected players would stand for the anthem.

In the memo, obtained by the Associated Press, Deputy Commissioner Mark Tatum suggested teams use their opening games “to demonstrate your commitment to the NBA’s core values of equality, diversity, inclusion and serve as a unifying force in the community.”

He recommended an address by a player or coach to fans before the anthem, or a video featuring players or community leaders speaking about important issues and showing photos from past community events.

The league’s preseason schedule begins Saturday with two games, including the NBA champion Golden State Warriors hosting Denver.

Tatum said the league supports and encourages players to express their views on matters that are important to them, while reminding of the rule that players, coaches and trainers stand respectfully for the anthem.

“The league office will determine how to deal with any possible instance in which a player, coach or trainer does not stand for the anthem. (Teams do not have the discretion to waive this rule),” the memo says.

The memo builds on discussions held by the NBA’s Board of Governors this week, and follows up on one Silver and players association Executive Director Michele Roberts sent to players recently.

It recommends that teams organize internal discussions to hear the players’ perspectives, if they haven’t already, and to start or expand programs within their communities.

“The players have embraced their roles in those efforts and we are proud of the work they do in our communities,” Tatum wrote.

The memo was first reported by ESPN.com.

Thunder keep Westbrook

Russell Westbrook is staying with the Thunder.

The superstar point guard and reigning NBA MVP has signed a contract extension to remain in Oklahoma City, the team announced Friday. ESPN first reported the agreement and said it would be for five years and worth $205 million.

Westbrook made an Instagram post Friday afternoon, a photo of him yelling at Chesapeake Energy Arena with his arms raised in the air. His words of choice to go with the photo are the words he lives by and the name of his charitable foundation: “WHY NOT??”

Falling behind on leading

After saying he needed to be more of a leader on a rebuilding team, Atlanta Hawks guard Dennis Schroder was arrested on misdemeanor battery charges Friday for a fight outside a late-night restaurant.

Brookhaven police reported Schroder and three other men were charged in the altercation, which occurred around 2 a.m. Friday at the 6am restaurant.

According to a police report, the video showed seven people, including alleged victim Joey Hall and a security officer, involved in “what appeared to be a verbal heated exchange.”

“Later in the video you can see [Schroder] initiate physical contact [shove] with Hall,” the report said. “Securities attempt to shield Hall was unsuccessful. Later in the video, you could see all the offenders attacking Hall. ... Security eventually was able to separate all involved parties. ”

Schroder, 24, was released on bond and is traveling with the team to Miami for its first preseason game Sunday night.

“We are still gathering information as it pertains to the situation, and out of respect for the legal process, we will have no further comment at this time,” the Hawks said in a statement.
