FOXBOROUGH, Mass. -- A frightening moment here in Gillette Stadium:

Gaither

Baltimore Ravens left tackle Jared Gaither was strapped to a gurney and rolled off the field after lying on the turf for about 15 minutes in the second quarter. Gaither's facemask was unfastened from his helmet, which was left on.

Replays showed the crown of Gaither's helmet rammed into quarterback Joe Flacco's back while pass blocking.

Gaither did have movement in his hands as he lay on the field.

I'll share an update when the Ravens release one.

Rookie right tackle Michael Oher has been flipped to the left side.
