Injuries strike three starting tackles

GLENDALE, Ariz. -- Offensive linemen keep falling.

The Vikings have lost right tackle Phil Loadholt to a shoulder injury. His return is questionable. The Cardinals, already without left tackle Mike Gandy, briefly lost right guard Deuce Lutui, who returned for the next series.

Vikings left tackle Bryant McKinnie just left the game. Not sure if it's serious, but three of the four projected starting tackles in this game are not playing.

Not having both starting tackles could give the Cardinals' pass-rushers a needed edge.
