49ers vs. Bills: San Francisco RB Brandon Jacobs 'ready to play'

San Francisco running back Brandon Jacobs has yet to play a regular-season down for his new team, but he believes his injured knee is well enough for him to take the field for the 49ers. Jacobs has been limited since Aug. 18 with the knee issue.

Jacobs has declared himself healthy enough to see action, according to mercurynews.com:

"I’m ready to play," Jacobs said, with sweat running down his face.

The eight-year veteran also went on to describe the motivation for his desire to return to the field as soon as possible:

"I want to get hit," Jacobs said. "I definitely want to get out and get hit because once you get out and get that first nice hit, you feel like you’re ready to go."

The former New York Giant has rushed for 4,079 yards and 56 touchdowns in his career. The Niners are hoping he can provide some carries in support of top running back Frank Gore, who has seen his production diminish in each game as the season has gone on. Gore rushed for a season-low 62 yards on a season-high 21 carries against the Jets.

The Niners host the Buffalo Bills in Week 5.
