Well, it wasn't the Harden elbow, and it wasn't much, but it probably was intentional and it definitely wasn't nice. Metta World Peace (the irony of the name is inescapable) continued his legendary history of borderline unnecessary fouls Sunday night with this tap to Jeremy Lin's face.
The fact that this comes against the same team as Harden is coincidental, but it's kind of a funny coincidence nonetheless.
At least he went to check on him, after he nailed Harden in a "celebration" he just kind of preened and walked away. This will of course be subject to review by the NBA on Monday morning.
