Big Ten rivals square off in Happy Valley, one looking for its first conference victory and another hoping to make it 2-0 as No. 19 Illinois visits No. 9 Penn S

This group, and Penn State's defense as a whole, will face its most difficult work yet Saturday. The undefeated Illini are led on offense by resurgent quarterback Luke Altmyer, who has morphed from a turnover liability into one of the most efficient QBs in the Big Ten (10 touchdowns, 0 interceptions).

Penn State has played in two noon kickoffs this year, winning both against West Virginia and Bowling Green. The Lions won 34-12 on the road against the Mountaineers through a two-hour-and-19-minute weather delay, while they narrowly pulled away from Bowling Green 34-27 thanks to a second-half comeback.
