The Washington Redskins’ rookie tandem of quarterback Robert Griffin III and running back Alfred Morris are re-writing the NFL’s record books early this season.

Griffin and Morris each rushed for their fourth touchdowns of the season Sunday. They became the first pair of rookie teammates in NFL history to rush for four touchdowns each in their team’s first four games, according to the Elias Sports Bureau.

It’s the first time since the 1970 league merger that the Redskins have had two players – rookie or veteran — with four rushing touchdowns apiece in their first four games.

Griffin and Morris are in a three-way tie with Houston’s Arian Foster for first in the NFL in rushing touchdowns.

Morris leads all rookies in rushing with 376 yards through four games, and Griffin is second with 252. Tampa Bay’s Doug Martin ranks third with 247 rushing yards.
