Coach Jim Harbaugh said he has no plans to change Brandon Jacobs' role. The 49ers have the league's No. 2 rushing offense and are averaging 5.88 yards per carry as a team. Harbaugh is not going to back off his rotation of Frank Gore and Kendall Hunter. "I think that's all decided on the field," he said when asked if Jacobs will be getting a chance anytime soon.

Brandon Jacobs didn't play an offensive snap in his 49ers debut in Week 7. Jacobs was active for the first time in 2012 after battling knee issues all year, but there just isn't anywhere to play him with Kendall Hunter running well behind Frank Gore. The 49ers didn't have any goal-line looks, and that may have been the only spot we would have seen Jacobs make an appearance.

49ers declared RB Brandon Jacobs, RB LaMichael James, WR A.J. Jenkins, QB Scott Tolzien, S Trenton Robinson, OG Joe Looney and DT Ian Williams inactive for Week 6 versus the Giants. Jacobs has been taking full practices for two weeks, but he's not going to get a chance to face his former team. Anthony Dixon gets the nod as the third running back due to his special teams value. Frank Gore won't have to worry about Jacobs vulturing goal-line opportunities for another week.

Brandon Jacobs (knee) practiced in full all week, but is listed as questionable for Week 6 against the Giants. Jacobs' Week 6 status is uncertain after he practiced fully all last week, then was inactive against the Bills. We won't know much more until game day.

A day after expressing frustration with his role in San Francisco, Brandon Jacobs has backtracked entirely. Jacobs has had a couple of conversations with coach Jim Harbaugh this week, and now believes it would not be "smart" to rush back into the lineup. "We ironed it out. We got it done," said Jacobs. "I understand where coach is coming from. Coach understands me with him playing football and understanding the athlete and the competitive nature of wanting to get out and help the team win ... What's important is the long run."

Brandon Jacobs says he's frustrated in San Francisco. "Oh, very. Because I don't know anything. I don't know what's what," Jacobs said. "But I'm hanging in there. ... Let's say I'm just working and doing what I have to do and that's that." Jacobs said he was ready to return from his knee injury last week, but coach Jim Harbaugh insisted he was "still not quite there." Jacobs practiced Wednesday, but Harbaugh has been noncommittal on his Week 6 status. Jacobs' frustration is understandable, but with Kendall Hunter running well behind Frank Gore, he's an unneeded luxury for the Niners.

According to coach Jim Harbaugh, Brandon Jacobs (knee) didn't make his 2012 debut Sunday because he's "still not quite there." Jacobs got in a slate of full practices last week, so the issue might be more that the 49ers don't really have a place for him in the game-plan with Kendall Hunter running well behind Frank Gore. Jacobs will likely make his 2012 debut against the Giants on Sunday, but unless he's installed as the exclusive goal-line back, he should remain well off the fantasy radar.

49ers declared RB Brandon Jacobs, RB LaMichael James, WR A.J. Jenkins, NT Ian Williams, QB Scott Tolzien, OG Joe Looney and S Trent Robinson inactive for Week 5 versus the Bills. Jacobs declared his knee 100 percent healthy, but the 49ers are giving him another week to shake the cobwebs loose. Frank Gore owners won't have to worry about Jacobs vulturing scores against the Bills' shaky run defense.

According to USA Today, Brandon Jacobs (knee) will be inactive for Sunday's game against the Bills. Jacobs won't threaten Frank Gore's goal-line workload in this one. Per the USA Today's source, the ex-Giant "should" be ready to make his Niners debut in Week 6.

Brandon Jacobs (knee) is listed as questionable for Week 5 against the Bills after completing a full week of practice. Jacobs practiced the most he has all season this week and is expected to be available for short-yardage work on Sunday. He could vulture a goal-line score.
