NACOGDOCHES, Texas - Tyler Sievertsen is still perfect as the new place-kicker at the University of Northern Iowa.

Sievertsen booted two field goals and converted all four of his PATs Saturday night as the third-ranked Panthers clipped No.12 Stephen F. Austin, 34-23, at Homer Bryce Stadium.

Sievertsen graduated from Cedar Rapids Kennedy in 2009 and is a redshirt sophomore at Northern Iowa.

Sievertsen kicked field goals from 43 and 21 yards against Stephen F. Austin. He booted two fields in a 20-19 loss at Iowa State last week and is 4-for-4 this season. He's also 5-for-5 on PATs.
