San Francisco 49ers linebacker Aldon Smith, who was arrested at early Friday morning on suspicion of DUI, is out "indefinitely" to seek treatment and will not play on Thursday, the team said on Sunday.

Jed York, the 49ers CEO, made the announcement after the team's 27-7 loss on Sunday to the Indianapolis Colts. Smith played on Sunday and recorded five tackles, but he won't play next week against the St. Louis Rams.

According to CSNBayArea's Matt Maiocco, Smith read a statement apologizing and admitted that he has a "problem."

Fox Sports' Jay Glazer reported earlier on Sunday that Smith could enter drug rehab “as early as this week." The team, league and NFL Players Association have agreed that Smith needs treatment. But according to ESPN’s Chris Mortensen, they decided to wait until after Sunday's game to take any action. Smith cleaned out his locker immediately following the 49ers' loss on Sunday.

Smith's arrest on Friday was the second alcohol-related incident of his three-year NFL career.
