STATE COLLEGE, Pa. (AP) — Caleb Komolafe ran for 72 yards and a touchdown and Northwestern held on to beat Penn State 22-21 on Saturday. Preston Stone threw for 163 yards with a touchdown to Griffin Wilde and Jack Olsen kicked three field goals for the Wildcats (4-2, 2-1 Big Ten) who won their third straight. The Wildcats, who hadn’t won in Beaver Stadium since 2014, took the lead for good with 4:51 when Komolafe bulled his way through Penn State’s defense to cap a 75-yard drive late in the fourth quarter. Penn State QB Drew Allar returned for his senior season to make better on the season-ending interception he threw in last season’s College Football Playoff semifinal against Notre Dame. Now, the 6-foot-5, 235-pound quarterback will spend the rest of the year watching after suffering what appeared to be a left ankle injury on Penn State’s final drive. Allar, Nicholas Singleton and Kaytron Allen ran for touchdowns for the Nittany Lions (3-3, 0-3), who lost their third straight. It was the fifth time a Franklin coached Penn State team has lost at least three consecutive games in a season.
