SANTA CLARA -- It turns out Aldon Smith's participation in the 49ers' victory over Detroit was an accomplishment in itself. For good measure, the second-year linebacker added seven tackles and at least one sack during his second game as a starter -- all after being involved in a serious car accident less than 48 hours earlier.

"Being able to go out and have fun and do something that I love doing, it was a relief to be able to get away from everything," Smith said Tuesday of playing in the 27-19 victory over the Lions on Sunday.

A one-inch cut under Smith's right eyebrow marks the extent of his injuries from the crash. Smith was a passenger in a single-car crash at 11:45 p.m. Friday near his home in San Jose's eastern foothills, a CHP spokesman confirmed Tuesday.

The unidentified driver of the car suffered a broken back after allegedly swerving to avoid a deer, according to CHP spokesman D.J. Sarabia. The driver was transported to San Jose Regional Medical Center, and Smith was taken to Stanford Hospital to receive "a few stitches" for a cut above his eye.

"Everybody's good," Smith said when asked about the driver's condition. "We all walked away from it. The only thing messed up was the car."

The incident occurred on Mount Pleasant Road, where "a deer ran out in front of them, they swerved to avoid the deer and then hit a tree," Sarabia said. The crash was first reported by the Sacramento Bee on Tuesday morning.

"We're aware of the accident, and Aldon communicated almost immediately with the team about it," 49ers spokesman Bob Lange said.

Neither alcohol nor drugs is considered a factor in what the CHP termed a "routine traffic collision."

Smith was involved in two other off-field incidents this year. He suffered stab wounds at a June 30 party at his home while allegedly breaking up a fracas in which two other partygoers got shot.

Smith also was arrested for drunken driving in Miami Beach during Super Bowl week in January, and that charge was reduced to reckless driving as Smith qualified for a first-time offenders program, the Bee reported.

Is this becoming an alarming pattern?

"I'm just focused on moving forward," Smith replied. "If I saw a pattern with a teammate, and he was able to make plays and play a good game, that's what I'm worried about. I'm worried about how he plays the game. I'm worried about how he helps out this team. I'm worried about the wins we're getting."

Was Friday night's incident simply being in the wrong place at the wrong time?

"Not really. It's life," Smith responded. "You can sit here and make it what you want."

Two days after the crash, Smith contributed to the 49ers' victory (a second sack is pending review by the Elias Sports Bureau) and gave no indication after the game that he was involved in the car accident.

Smith, who turns 23 on Sept. 25, totaled 14 sacks last season and was runner-up in NFL Defensive Rookie of the Year voting behind the Denver Broncos' Von Miller. Smith was the 49ers' first-round draft pick out of Missouri.

Smith has moved into a starting role this season after being a situational pass-rusher last season. Smith had a sack in the season-opening win at Green Bay, giving him 101/2 sacks in his past nine games, including a sack in each of the 49ers' two playoff games.

"Trying to catch a rhythm, trying to keep the rhythm," Smith said of his sack spree.
