INDIANAPOLIS – For the fourth time in 2 1/2 years, a 49er faces a charge of driving under the influence.

Backup offensive lineman Al Netter was arrested early Wednesday after a traffic stop in San Jose. According to the California Highway Patrol, an officer observed Netter's car weaving around 3 a.m. about a mile from the 49ers' practice facility in Santa Clara.

The 49ers, through a spokesman, issued a statement Saturday: "The 49ers are aware of the recent matter involving Al Netter. We take these issues very seriously, but will reserve comment at this time as this is an ongoing legal matter. The organization will continue to gather the facts and monitor the developments closely."

Netter, 23, is from Rohnert Park and played at Northwestern. He joined the 49ers as an undrafted free agent last year and spent the season on the practice squad.

He is one of four practice squad players who turned down an opportunity to join another team's 53-man roster – which comes with higher paychecks – in the belief their long-term futures were better with San Francisco.

Netter re-signed with the 49ers earlier this year and will compete with 2012 draft pick Joe Looney and Elk Grove's Kenny Wiggins for a roster spot in the upcoming season.

In 2010, defensive end Ray McDonald was cited for DUI. Last year, outside linebacker Aldon Smith and defensive end Demarcus Dobbs were arrested on suspicion of DUI. Smith entered a program to reduce his charge to reckless driving.

Harbaugh backs Callahan – Jim Harbaugh weighed in – forcefully – for former Raiders coach Bill Callahan regarding Tim Brown's claim that Callahan's game plan switch "sabotaged" the Raiders in Super Bowl XXXVII in 2003.

Brown said the Raiders originally planned a run-first attack against the Tampa Bay Buccaneers but switched late in the week to a more pass-oriented plan. Not true, said Harbaugh, who was a Raiders assistant that season.

"I totally concur with everything he said," Harbaugh said, referring to Callahan. "(Brown) was not factual at all, and I really think he should be ashamed of what he said."

All in the family – Colorado's David Bakhtiari, one of the more athletic offensive tackles in the draft, had a personal trainer as he prepared for the combine – his brother Eric, who played five games at outside linebacker for the 49ers in 2012.

Who's the best athlete in the family?

"My sister," David, from Burlingame, said of Danielle. "My brother and I used to always talk about it, and at the end of the day, she's a stud."

David Bakhtiari likened himself to 49ers left tackle Joe Staley, who was Eric's housemate when he was with the 49ers.
