It wasn’t the sharpest of nights for Rex Grossman.

The veteran quarterback completed only 2 of 10 passes for the Washington Redskins in their preseason opener Thursday night against the Buffalo Bills. The offense didn’t score with Grossman at quarterback after he took over for rookie starter Robert Griffin III.

Grossman did manage a 25-yard completion to wide receiver Josh Morgan.

Rookie Kirk Cousins took over at quarterback late in the second quarter.
