49ers pregame notes: Jacobs, Ginn inactive

GREEN BAY, Wisc. -- Running back Brandon Jacobs and return man Ted Ginn were among the 49ers' seven inactive players announced 90 minutes prior to the team's regular-season opener against the Green Bay Packers at Lambeau Field.Kyle Williams will return punts for the 49ers. The 49ers could use Perrish Cox as the backup punt returner. Kendall Hunter is expected to handle the kick-return duties.
Neither Jacobs nor Ginn practiced last week as they continued to rehab injuries they sustained in the exhibition season. Jacobs sprained his left knee sprain Aug. 18 at Houston, while Ginn sustained a right ankle sprain Aug. 26 at Denver.First-round draft pick A.J. Jenkins is active, while running back LaMichael James, selected in the second round, will have to wait at least another week for his NFL debut. He was declared one of the 49ers' inactive players.Here is a look at the inactive players:49ers inactives

When the 49ers shift to six defensive backs, Perrish Cox will enter the game, 49ers defensive coordinator Vic Fangio confirmed last week.Colin Kaepernick's family, who moved from Wisconsin to Turlock when he was 4 years old, had a prime tailgate spot prior to Sunday's game in the shadow of Lambeau Field.Now, the question is whether they get a chance to see Kaepernick get on the field?Offensive coordinator Greg Roman left the door open last week to the possibility that the 49ers might run some read option with Kaepernick. The 49ers showed some of those plays in the exhibition season, including a play that resulted in Kaepernick's 78-yard touchdown run against the Minnesota Vikings."The read option is a good football concept and it's something that we've done," Roman said last week. "You can do it a lot of different ways, there's a lot of different ways to do it. I've seen other teams do it. So, it's a football play like any other and it can be run at any time."We reported last week that the 49ers were 1.25 million under the salary cap. That number now stands at 936,923 after factoring in an injury settlement for tight end Nate Byham, a league source told CSNBayArea.com.Byham was released after undergoing surgery to repair a frayed meniscus in his left knee. Teams cannot release an injured player without a settlement. The 49ers agreed to pay Byham the equivalent of four weeks of regular-season pay. Byham is expected to be healthy in another month. He can sign with any team, but the 49ers are prohibited from re-signing him until Week 5.
