WASHINGTON — Washington Wizards star Gilbert Arenas pleaded guilty Friday to carrying a pistol without a license in the District of Columbia, a felony conviction that could jeopardize his future in the NBA.

Arenas pleaded guilty to a single count of violating the city's strict gun laws as part of a plea bargain in D.C. Superior Court.

The charge stems from a Dec. 21 incident in which Arenas admitted that he stored guns in his locker at the Verizon Center and took them out to play a joke on a teammate.

The NBA has suspended him indefinitely.

A pre-sentence report is not yet complete, but defense attorney Kenneth Wainstein said Friday that prosecutors have agreed not to seek a sentence longer than the low end of sentencing guidelines. That means Arenas likely faces no more than six months behind bars.

Arenas "accepted full responsibility for his actions, acknowledged that those actions were wrong and against the law, and has apologized to all who have been affected by his conduct," Wainstein said in a statement.
