The 49ers have ruled out receiver Pierre Garcon Vita Vea Jersey , who has a knee injury.Garcon has played in only one of the past four games. Kendrick Bourne is expected to start again in his place, with Dante Pettis seeing more snaps.鈥淲e need those guys to step up,鈥?49ers coach Kyle Shanahan said, via Matt Maiocco of NBC Sports Bay Area. 鈥淣ot just the receivers, but same thing with our tight ends and our backs out of the backfield. They need to help us out in the pass game, and if they do that and we can stay balanced in the run game, that鈥檚 how you avoid turnovers and take the pressure off everyone and have your best chance to score.鈥滸uard Joshua Garnett (thumb) also won’t play.Linebacker Reuben Foster, who missed the two games before the open date with a hamstring strain, is questionable. He will work out before the game to determine his availability, Shanahan said. It’s looking less and less likely that 49ers linebacker Reuben Foster will be playing for the 49ers on Sunday.Foster Carlton Davis Jersey , arrested on Saturday night in Tampa on one count of misdemeanor domestic violence, remains in jail on Sunday morning, according to Matt Maiocco of NBC Sports California. Foster will appear before a judge, by video monitor, at some point this morning. Bail likely will be set at that time.The 49ers have issued no statements about Foster, and no comment about the situation appears on the team’s Twitter page or official website. When Foster faced domestic violence charges in the offseason, the team seem prepared to move on from the 2017 first-round draft pick if he were found to be legally responsible. After the alleged victim recanted, the case against Foster fell apart.Foster had been listed as questionable for the game against the Buccaneers with a hamstring injury.
