WASHINGTON — Straight-faced and subdued, Washington Wizards star Gilbert Arenas pleaded guilty Friday to a felony gun charge connected to a locker-room argument, leaving his All-Star career in limbo and his freedom in doubt.

Arenas won't know whether he must serve jail time until his March 26 sentencing and remains free until then. The government indicated it will not seek more than six months, although the judge can give Arenas anywhere from probation to the charge's maximum term of five years. Guidelines call for six to 12 months.

Arenas did not speak to reporters on the way into D.C. Superior Court — only shaking his head when asked if he wanted to tell fans anything — or when he walked down the block to police headquarters after his 20-minute hearing.
