Nebraska is shooting for a 2019 walk-on class of between 20 and 25.
The Huskers added No. 6 on Thursday afternoon.
Kearney Catholic lineman Eli Richter announced he plans to walk on and play football at NU, making his pledge public via Twitter.
Richter, listed at 6-foot-5 and 245 pounds, has just the kind of frame that the Huskers covet.
A two-way lineman for the Stars, Richter has been credited with 81 tackles and nine sacks and has forced three fumbles in eight games as a senior, according to MaxPreps.
Richter earned Class C-1 Super-State honors from the Journal Star as an offensive lineman his junior year and has good athleticism, running in the 4.8-second range in the 40-yard dash.
Richter first earned a walk-on offer in early October and also had interest from some Division II schools.
He joins linemen Matt Huser (Millard West) and Riley Moses (Fillmore Central), defensive back Cam Kleinschmidt (Lincoln High) and specialists Grant Detlefsen (Lincoln Southeast) and Dylan Jorgensen (Lincoln Southwest) as known walk-ons so far this year for the Huskers.
