Jim Harbaugh said he "expects" Aldon Smith, who had his second DUI arrest in a year and a half on Friday, will be on the field today against Indianapolis. But the team's starting outside linebacker may not be the full-time player he was in the first two games. NFL Network's Ian Rapoport reported this morning that Smith may play "sparingly."
More national reports said the 49ers would seek help for Smith, who has steadily shown up in a number of police reports since January 2012. Fox Sports reported that Smith could begin a rehab program as early as this week. No decision has been made on the matter, however.
Smith played 100 percent of the defensive snaps in Week 1 and 91 percent in Week 2 as he battled through a back injury. He was limited in practice this week and is listed as probable on the team's injury report. Smith leads the 49ers with 3 1/2 sacks. If he came out of the game, rookie Corey Lemonier and Dan Skuta would be available to replace him.
Smith, 23, was arrested at 7 a.m. Friday in San Jose after he went off the road and into a residential front yard. Smith, according to neighbors, was sleeping with his foot still on the accelerator, causing the tires of his truck -- pinned against a small tree -- to spin and smoke. He was arrested for suspicion of DUI and marijuana possession. He was released from jail three hours later and practiced with the team that afternoon.
