The San Francisco 49ers placed linebacker Aldon Smith on the reserve/non-football injury list Monday.
Smith was arrested Friday on suspicion of DUI. He started Sunday's game against the Indianapolis Colts. He flew to a treatment center Monday, according to NBC Sports' Pro Football Talk. It is not clear where he headed, but he will spend the next several weeks getting treatment.
"Aldon Smith is taking a leave of absence to address a personal matter," general manager Trent Baalke said in a statement. "The 49ers organization both respects and supports Aldon's decision and commends him for taking responsibility for his actions. The long-term well-being of our players is paramount and we will stand by Aldon as he works toward addressing this issue. Due to the private nature of the matter, we will have no further comment."
Smith is out indefinitely, starting with Thursday's game at St. Louis.
"I am taking a leave of absence to address my health," Smith said in a statement. "I am sorry that I have affected my team, my family and the organization. I will do everything in my power to handle this situation the best way possible. I appreciate the support of the 49ers and our fans."
Team CEO Jed York announced after Sunday's 27-7 loss to the Colts that Smith would enter rehab.
Smith still could be suspended by the league at some point. York said there is no timetable for his return.
San Jose police Sgt. Heather Randol told ESPN that marijuana was not found in Smith's car but unidentified prescription drugs were after Smith crashed his car into a tree. He was arrested after the accident at 7 a.m. Friday. He was not injured.
"We're very fortunate that nobody got hurt, Aldon included and anybody else," York said. "We want to make sure that Aldon's never in a position like this again."
York said he discussed the situation with Smith, and he agreed to seek help.
"In talking with Aldon and knowing what he wants to do, there's not a one-day fix," he said. "This is a long-term fix. We support Aldon. If Aldon's willing to fight for himself and make this right, I will stand here and I will support him."
York was criticized by some for allowing Smith to play in Sunday's game.
"Sitting someone down and paying them to sit down when they're going to seek treatment in the future -- that didn't seem like an appropriate punishment," York said.
Also, 49ers running back Frank Gore was not happy with coach Jim Harbaugh after Sunday's 27-7 loss to the Indianapolis Colts at Candlestick Park.
Gore "had choice words for Harbaugh near the end of the game, as (he) was heading out to the field," tweeted SFGate.com's Kevin Lynch after the game.
It is not clear what was said or exactly what Gore was upset about.
Gore had 11 rushes for 82 yards and two catches for 21 yards, but had just four touches in the second half.
--The Ohio State Highway Patrol cited Cincinnati Bengals cornerback Adam "Pacman" Jones with disorderly conduct early Monday morning.
Jones, who celebrated his 30th birthday on Sunday, is alleged to have made offensive comments while drunk, USA Today reported.
About 2:30 a.m., the Ohio Highway Patrol stopped a car that Jones was a passenger in, according to the police report. The driver, a 33-year-old woman, was stopped for driving 60 mph in a 45 mph zone and eventually charged with operating a motor vehicle under the influence.
Jones was released and has a Friday court date. The disorderly conduct charge is a misdemeanor.
--Chicago Bears defensive tackle Henry Melton is out for the year with a torn ACL, ESPN reported. Melton was injured during Sunday night's win over the Pittsburgh Steelers.
The 26-year-old was playing with a one-year contract at $8.45 million as the team's designated franchise player. Melton has been one of the best defense players for the Bears, and now he will enter free agency next year with some uncertainty.
"You can't replace a Henry Melton," outside linebacker Lance Briggs told the Chicago Tribune. "He is an elite D-lineman. He will be missed. The next man has to step up and do his job."
--Tampa Bay Buccaneers coach Greg Schiano said he did not fly back with the team on Sunday night because he was tending to his ill father.
