Reports: Niners' Smith surrenders to cops

Santa Clara, CA ( - San Francisco 49ers linebacker Aldon Smith reportedly turned himself in to authorities on Tuesday night after being charged with three felony counts of possession of assault weapons earlier in October.

According to multiple media outlets, including the San Jose Mercury News, Smith, who is currently on an indefinite leave of absence from the 49ers to seek help for a substance-abuse problem, posted a bail of $75,000 after turning himself in at the Santa Clara County jail on Tuesday.

Smith faces a court date for the weapons charges on Nov. 12, just one week before he's scheduled to be in court to face misdemeanor DUI and drug charges resulting from his Sept. 20 arrest on suspicion of driving under the influence and possession of marijuana.

The weapons charges against Smith stem from a 2012 party the All-Pro linebacker hosted where he was stabbed and two others were shot. The cops found assault rifles, magazines and ammunition at the party.

On the field, Smith has been one of the NFL's premier pass rushers since being taken by San Francisco with the seventh overall pick of the 2011 draft. He notched 14 sacks during his rookie season, then ranked second in the league with 19 1/2 sacks last year while helping the 49ers to an appearance in Super Bowl XLVII.
