Celtics swingman Jeff Green and fellow Georgetown product Greg Monroe gave pointers to 10 Marines from the Wounded Warrior basketball program before their game on the south lawn of the White House on Wednesday. President Barack Obama also made an appearance, according to the White House blog.

No word on whether Obama challenged Green to a game of 1-on-1 (insert joke about how the Celtics would be better off with the President on their roster).

Green will also take place in the Celebrity Soccer Challenge in Washington D.C. on Sunday, hosted by former Red Sox shortstop Nomar Garciaparra and his wife Mia Hamm. Among the other celebrities are Lakers guard Kobe Bryant, U.S. Women’s World Cup star Alex Morgan and “Around the Horn” host Tony Reali. Wait, who?

Now, if only Green can slide tackle Kobe, he’ll finally ingratiate himself to Celtics fans.
