Backup running back Brandon Jacobs and Ted Ginn Jr. will both have to wait at least another week to make their season debuts for the San Francisco 49ers.
Both are on the inactive list against the Minnesota Vikings after being listed as questionable Friday. Ginn has been bothered by a right ankle injury and had said earlier in the week that he hoped to play Sunday. Jacobs has yet to play this season because of an injured left knee.
The Vikings scratched starting linebacker Erin Henderson because of a concussion sustained last week against Indianapolis. Marvin Mitchell started in Henderson’s place.
Rookie receiver Jarius Wright has also been scratched. He missed the first two games with an ankle injury but was listed as probable Friday.
