LOS ANGELES -- Metta World Peace has no interest in making a bury-the-hatchet peace gesture with Oklahoma City's James Harden at the onset of the Los Angeles Lakers' Western Conference semifinals series against the Thunder.

"I don't shake substitutes' hands," World Peace said after contributing 15 points, five rebounds and four steals in the Lakers' 96-87 Game 7 victory over the Denver Nuggets on Saturday in his first appearance since serving a seven-game suspension for his elbow to Harden's head last month.

Harden is not just any substitute of course, he's the Sixth Man of the Year who suffered a concussion in the second quarter of the Lakers' 114-106 double-overtime win over the Thunder on April 22 after World Peace's elbow following a dunk dropped him to the floor.

World Peace issued a statement of apology following the incident and told reporters in his first public comments about the suspension nearly two weeks ago that he reached out to check on Harden's health through a third party.

However, World Peace has yet to contact Harden directly and said that he has no plans to even acknowledge the Thunder's versatile wing player on the court before Game 1 on Monday.

"My concern is executing the coaches' game plan and that's what my concern is," World Peace said when asked if he had any thoughts about facing Harden for the first time since the suspension.

The mercurial Lakers forward went on to say that the entire Thunder team has a habit of ignoring the common NBA ritual of showing mutual respect before tipoff with a handshake or fist pound.
