Tony Romo failed to make it through the third quarter of the Cowboys' battle at home against the Redskins tonight after a sack by Keenan Robinson left the Dallas quarterback unable to rise from the turf for several minutes.

Romo has led the Cowboys thus far to a 6-1 record on the season, after a 2013 in which he was knocked out for the season by a back injury. ESPN reported trainers were looking at Romo's back again tonight.
