EAST RUTHERFORD, N.J. — Patriots rookie wide receiver Demario Douglas suffered his second head injury of the season Sunday when he was hit hard to the head and neck area by linebacker Cam Brown on a punt return.

Douglas briefly laid motionless on the field before standing up, taking his helmet off and walking to the Patriots’ blue pop-up medical tent. He quickly walked to the locker room and was initially ruled doutbful to return before being declared out.

Douglas has been one of the few bright spots for the Patriots’ offense all season. He caught six passes on nine targets for 49 yards and returned three punts for 9 yards before leaving the game.

Douglas, a sixth-round draft pick out of Liberty, leads the Patriots with 410 receiving yards on 36 receptions.

He suffered a concussion Week 5 against the Saints and missed the Patriots’ next game against the Raiders.
