If the 49ers are going to make good on running back Carlos Hyde‘s prediction of a Super Bowl run in 2018, it would help to have linebacker Reuben Foster on the field for the entire season. Foster, one of the team’s two first-round picks this year, joined the team while rehabbing a shoulder injury, missed time with an ankle injury, dealt with a rib injury and left the last two games after suffering stingers. 49ers coach Kyle Shanahan said those stingers are unrelated to the previous shoulder injury, but added that the team would like to find ways to limit the injuries incurred by both Foster and rookie safery Adrian Colbert in 2018. Colbert has also dealt with several nagging injuries this season.
