Quarterback Marcus Mariota was named the NFL Rookie Offensive Player of the Month for September, the league announced today.

Mariota, a University of Oregon graduate and the Tennessee Titans’ top pick in the April NFL Draft, topped all rookies in passing yards (833), touchdown passes (eight) and passer rating (109.2).

With eight touchdown passes in September, Mariota tied Mark Rypien for the most by any player in his first three games in NFL history. The eight touchdowns tied Mariota for fourth-most in the league this season.

Mariota passed for at least 200 yards and two touchdowns in all three September regular-season games. His passer rating of 109.2 is the second-highest of any rookie quarterback through Week 3, the NFL said, behind Greg Cook of Cincinnati in 1969.

Mariota became the first rookie in NFL history to post a 158.3 passer rating on Kickoff Weekend, the highest possible figure, in a 42-14 victory over Tampa Bay.

Mariota and the Titans have an open date on the schedule this week before resuming play next week hosting Buffalo in Nashville Oct. 11.

Bills’ cornerback Ronald Darby was named the Defensive Rookie of the Month.
