Luka Doncic can apparently sink baskets with his hands AND his head ... 'cause check out this trick shot he made Monday night -- he used his noggin and got nothing but net!!
The Dallas superstar and his teammate, Dwight Powell, were messin' around before the Mavs took on the Grizzlies at the FedEx Forum in Memphis ... when they decided to put on a little show for the fans in attendance.
First, Powell threw a basketball off Doncic's shoulder ... and then he headed it back to Doncic so the point guard could finish off the Globetrotters-esque play with a header of his own.
