49ers Linebacker Aldon Smith Suspected of DUI

San Francisco 49ers All-Pro linebacker Aldon Smith was released from jail Friday after his pickup truck apparently struck a tree and was arrested on suspicion of driving under the influence and marijuana possession, according to ESPN.

Smith later took to the practice field with his teammates Friday afternoon at team headquarters in Santa Clara. He is scheduled to appear in court on Nov. 4. Smith declined to comment when reporters asked about his arrest.

Coach Jim Harbaugh told reporters Friday that he expects that Smith will play Sunday when the Niners host the Indianapolis Colts at Candlestick Park. "I expect Aldon -- like today -- he'll be back to work and playing on Sunday," Harbaugh said. "I anticipate that, yes."

Harbaugh said that any potential discipline will likely come from the NFL. "There will be consequences. There always is," Harbaugh said. "Good or bad, we all have consequences."

Smith, 23, posted $5,250 bail and was released from the Santa Clara County jail late Friday morning, just hours after he was taken into custody by police responding to a single-vehicle crash that involved his truck in San Jose, Santa Clara County Sheriff's Sgt. Kurtis Stenderup said.

San Jose police arrested Smith after officers received a call from a resident about the crash in the city's Silver Creek area around 7 a.m., Sgt. Heather Randol said. Officers gave Smith breath tests and other tests after his pickup apparently struck a tree, hit a curb and left streak marks on a driveway and sidewalk.

"They conducted an investigation and determined he was under the influence," Randol said about Smith. "He was the only person inside the vehicle. "The linebacker, who helped the 49ers get to the Super Bowl last season, has 37 sacks in 34 career games and was selected to his first Pro Bowl and was an All-Pro last season.
