Penn State football's defense struggled against an unranked and winless UCLA offense in Week 6, and defensive coordinator Jim Knowles might be without another starter against Northwestern.
Alongside linebacker Tony Rojas, whose absence was detrimental to the defense against the Bruins, the Nittany Lions (3-2, 0-2 Big Ten) may not have cornerback Zion Tracy available on Saturday. Tracy was listed on the official injury report as questionable.
