The Vikings sustained no lasting injuries in a 23-20 loss to the Indianapolis Colts on Sunday. Percy Harvin experienced cramps during the game, but that's all they were, according to Jeremy Fowler of the St. Paul Pioneer Press. Harvin is expected to be at 100 percent Sunday.
Defensive end Brian Robison banged his elbow against the Colts, Vikings coach Leslie Frazier said, but he too is without any lingering issues from the incident.
Other than those two, Fowler reported that "everyone else on the roster is healthy."
The 49ers, too, avoided major injuries in their 27-19 win over the Detroit Lions on Sunday.
The Vikings kick off at home against the 49ers at noon CT Sunday on Fox.
