Los Angeles Lakers forward Metta World Peace called out Oklahoma City guard James Harden on Twitter on Sunday night.

Harden struggled shooting on Sunday night in the Thunder's loss to the Miami Heat, 91-85, making only 2 out of 10 shots for nine points. World Peace took the Sixth Man of the Year's poor shooting performance as an opportunity to make fun of him on the social media platform.

No brain All beard, the mercurial NBA player tweeted about Harden, who is known for a massive beard.

The verbal blow on Twitter comes after World Peace issued a physical blow to Harden a week before the playoffs began. World Peace elbowed Harden in the head during an April 22 game that left Harden with a concussion.

World Peace never apologized to Harden, though he did reach out through third parties to find out if he was okay, and has seemed to enjoy razzing the Thunder star.

Because I might have to play him in the playoffs, so I didn't really want to talk to him, World Peace told Conan O'Brien on why he didn't reach out to Harden. But I did make sure he was okay... I called some third parties and they told me he was doing okay.

The Thunder appeared to get the last laugh when they knocked the Lakers out of the playoffs, but that hasn't stopped World Peace from attacking Harden on Twitter.
