Smith (back) is active for Sunday's game against the Raiders.

The 49ers like to give Smith a lot of veteran rest during the week, but he was able to practice Friday and shouldn't be noticeably limited against Oakland. Feel free to use him as you normally would.

Smith (back) did not practice Monday, the Sacramento Bee's Matt Barrows reports.

He could still be able to take the field this week after recording three tackles (two solo) and a sack in Thursday's loss to the Seahawks. Continue to monitor his status throughout the week, as it may have just been an attempt to rest the veteran defensive end.

After a strong start to the season, then a lull between weeks 3 and 11, Smith has begun to turn it on over the past couple of weeks. He has recorded a sack in consecutive games and also forced a fumble last week. He will never put up huge tackle numbers, but he is beginning to look like the disruptive player we are used to.

Smith (back) did not practice Tuesday, the San Jose Mercury News reports.

Apparently, Smith suffered a back injury in Sunday's win over Washington, and his status for Thursday's game against Seattle is murky in light of his DNP Tuesday. The injury was news to defensive coordinator Vic Fangio, who may have to lean on Tony Jerod-Eddie or Tank Carradine on the right side of the line if Smith is unable to go.

The one they call "the cowboy" was a disruptive force yet again. The forced fumble was his first turnover created this season, and it compliments his 16 tackles and three sacks on the year. He continues to be a productive defensive lineman despite his rising age.
