BOSTON — Draymond Green will switch up his game-day routine a bit Thursday: between the Warriors’ optional morning shoot-around and their game against the Celtics, the two-time All-Star is speaking at Harvard.

Green is friends with a student at Harvard Business School, who connected him with one of her professors interested in having him visit campus. The event Green is speaking at Thursday afternoon is hosted by Harvard’s Institute of Politics and called, “Athletes as Leaders: A Discussion with Draymond Green.”

Initially slated for a classroom with a maximum capacity of about 150 students, the event was moved to a larger venue when more than 500 students signed up. It is scheduled for 1-2 p.m. ET, which allows Green plenty of time for his usual pregame nap before heading to TD Garden around 6 p.m. for an 8 p.m. tip-off.

“It definitely blows my mind to be speaking at Harvard,” Green said. “But then to be of interest like that, where people are really checking for it, that’s pretty interesting.”

Green, 27, sits on the advisory board for the Ross Initiative in Sports for Equality (RISE), a nonprofit that aims to improve race relations and drive social progress through sports. His $3.1 million donation to Michigan State for the Draymond Green Strength and Conditioning Center is considered one of the largest donations by an active athlete to his alma mater.

One of the NBA’s most loquacious players, Green has spoken openly numerous times about issues of social injustice.

Last month, as part of an Instagram post criticizing Houston Texans CEO Bob McNair for using the phrase “inmates running the prison” during NFL meetings about players protesting during the national anthem, Green wrote: “For starters, let’s stop using the word owner and maybe use the word Chairman. To be owned by someone just sets a bad precedent to start. It sets the wrong tone. It gives one the wrong mindset.”
