ATLANTA (AP) -- Devonta Freeman scored three touchdowns as the Atlanta Falcons remained unbeaten in the NFL, romping to a 48-21 victory over the hapless Houston Texans on Sunday.
Freeman, who took over as the starting running back after rookie Tevin Coleman sustained a rib injury in Week 2, has scored six TDs in the last two games. The Falcons improved to 4-0 for only the fourth time in club history.
Freeman had touchdown runs of 16, 23 and 6 yards. He set up another score with a 44-yard reception.
In New Orleans, Drew Brees hit C.J. Spiller with a short pass that the running back turned into an 80-yard touchdown -- the 400th of the Saints quarterback's career -- on the second play of overtime as the Saints beat the Dallas Cowboys 26-20 for their first win this season.
Brees, who missed New Orleans' previous game because of a bruised rotator cuff in his right (throwing) shoulder, completed 32 of 39 throws for 279 yards in his return. Mark Ingram gained 126 yards from scrimmage, and Khiry Robinson had a 1-yard touchdown run for New Orleans (1-3).
Joseph Randle scored the lone TD for Dallas (2-2) on a 1-yard run in the first half.
Cincinnati's Andy Dalton added to his streak of impressive games and big plays, throwing a 55-yard touchdown pass on the run as the Bengals remained unbeaten with a 36-21 win over the Kansas City Chiefs.
The Bengals (4-0) matched the third-best start in club history, two wins short of the club record.
