NEW YORK — An advertisement featuring the NBA's two biggest superstars includes a gun reference, the same week two players were suspended for carrying firearms to the locker room.

The Nike ad, which appears in several publications including Sports Illustrated and ESPN The Magazine, has LeBron James on one page and Kobe Bryant on the other. Along with the slogan, "Prepare For Combat," is a quote from each player showing how tough he is.

Bryant's blurb says: "I'll do whatever it takes to win games. I don't leave anything in the chamber."

The chamber in a gun is the compartment that holds the bullet before it is fired.

"The Nike print ad featuring Kobe Bryant was intended to illustrate his all out play and commitment on the basketball court," Nike said in a statement. "It is a commonly used reference for shooting the basketball and no offense was intended."

NBA commissioner David Stern is sensitive to the issue of gun violence, and the NBA criticized the ad.

"We had no prior notice of this ad," spokesman Tim Frank said. "We think it is inappropriate."

Gilbert Arenas and Javaris Crittenton were suspended for the remainder of the season Wednesday by Stern for having guns in the Washington Wizards' locker room.

Stern said during a conference call Wednesday that he and players' association executive director Billy Hunter would discuss a stronger gun policy than the one currently in the collective bargaining agreement, which prohibits players from having firearms on team property or business.

Bryant's agent, Rob Pelinka, did not respond to a request for comment.

The wording under the photo of a shirtless James reads: "Opposing teams don't realize I was a football player first. I can take those hits and give a few back too."

The ad features a far different look — the athletes' skin transformed to scaly armor — than Nike's spots featuring puppets in the likenesses of James and Bryant.

The current campaign was too much for Cleveland city officials, who rejected a proposal by Nike to erect a 10-story tall mural of a bare-chested James. Over his left shoulder would have been the words "Prepare for Combat," topped by the Nike trademark swoosh.

The city wanted the display to project a more positive tone and have a Cleveland reference.
