Vikings defensive back Josh Robinson will be out 4-6 weeks because of a fractured sternum he suffered in Sunday's loss against the Seahawks, Vikings head coach Leslie Frazier announced during Monday's press conference.
Frazier did not say whether they would place Robinson on injured reserve yet with six weeks left in the season. That option will be discussed today by the front office. Xavier Rhodes would replace Robinson as the starting left cornerback, and Marcus Sherels would be the nickel back.
Vikings center John Sullivan also suffered a concussion during the game and will go through the NFL's protocol on concussion-related injuries.
Frazier has not made a decision on the starting quarterback against the Packers on Sunday.
He also said that Adrian Peterson, who was hampered because of a groin injury Sunday, would be evaluated this week.
The Vikings play at Green Bay on Sunday.
