It appears that Jacobs, who has been inactive all of the regular season, is close to seeing his first game action after a hit injured his left knee in an Aug. 18 preseason game against the Houston Texans.

The 30-year-old veteran joined San Francisco this offseason following seven years spent with the New York Giants. The career 4,849-yard rusher's return to the 49ers gives coach Jim Harbaugh yet another option behind No. 1 running back Frank Gore and change-up back Kendall Hunter.

Late Monday night, Jacobs went on Twitter to thank fans for their support this season, then said he would stay off the social media website for the remainder of the season.
