Aldon Smith said that he has stayed completely sober since September when he was arrested and charged with drunken driving for the second time since January 2012.

"I've been able to maintain, and it's going good," Smith told reporters when asked about his sobriety. "I'm in the best shape I've been in coming into a camp, and my mind is probably in the best spot it's been in, so I'm feeling great."

 

Smith voluntarily missed five games last season when he entered a substance-abuse treatment center.

Smith will meet with Roger Goodell in the near future.

In October in London, Goodell told reporters that the league might consider Smith's aggressive approach to his problem could be considered when potential discipline would be addressed.

"That's in their hands," 49ers coach Jim Harbaugh said of a potential NFL suspension. "They will discipline if they feel he warrants it."

Smith was arrested for an alleged fake bomb threat at LAX and no charges were pressed.
