A convincing 45-10 win over then-No. 9 South Dakota State on Saturday has propelled the Illinois State football program up seven spots in both national Football Championship Subdivision polls to No. 15, as announced on Monday.

The Redbirds picked up their second win over a ranked opponent this season with the 35-point victory over the Jackrabbits. ISU currently ranks second in the country in scoring at 49 points per game and is first in the country in scoring defense, allowing just 7.8 points per game to opponents.

ISU garnered 1,570 points in The Sports Network FCS Top 25 and jumped seven spots to No. 15 overall, the highest jump for any team in this week's rankings. North Dakota State remained at the No. 1 spot after a narrow victory at Western Illinois.

The Redbirds also moved up seven spots to No. 15 in the FCS Coaches Poll, thanks to their dominant defeat of the Jackrabbits in both teams' conference opener. North Dakota State led the way in the No. 1 spot and was followed by Youngstown State (No. 10), Southern Illinois (No. 13) and Illinois State. South Dakota State dropped 10 spots to No. 19 and Northern Iowa fell 11 spots to No. 21, but still finished ahead of Indiana State at No. 22 despite losing to the Sycamores, who have knocked off ranked opponents the last two weeks.

Illinois State will travel to Terre Haute, Indiana, on Saturday, Oct. 11, for its first road contest of the season against Indiana State. Kickoff is scheduled for 2 p.m.
