Vikings take lead, lose two starters

MINNEAPOLIS -- The Minnesota Vikings have taken a 3-0 lead over the Green Bay Packers here at the Metrodome, but it has come at a price.

With the first quarter in the books, the Vikings have already lost right guard Anthony Herrera to a knee injury and linebacker Chad Greenway with what appears to have been a poke in the eye. Herrera has been replaced by Ryan Cook, and his return is doubtful.

Greenway, the Vikings' leading tackler, is standing on the sideline without a helmet. He's holding an ice pack on his right eye. We'll see if he returns. Heath Farwell has been playing in his spot, while Ben Leber is taking his spot in the nickel.

Meanwhile, Packers safety Anthony Smith has been carted into the locker room with an ankle injury.

UPDATE: Greenway has returned to the game after sitting out for part of the first quarter.
