Pittsburgh at Penn State

The winner in Beaver Stadium (WJLA-TV-7, WJZ-TV-13 at noon) keeps alive its hopes for a national championship... No. 2 Penn State (9-1), a 5 1/2-point favorite, brings in its most balanced offense since Joe Paterno became coach 17 years ago... Quarterback Todd Blackledge has completed 56 percent of his passes for 2,069 yards and 21 touchdowns. Tailback Curt Warner has rushed for 923 yards, gaining more than 100 in four of his last five games... No. 5 Pittsburgh (9-1) relies on the passing of Dan Marino, its all-time total offense leader. But a favorite receiver, John Brown, is one of three key Panthers questionable because of injuries. Brown has a knee hurt, offensive tackle Bill Fralic has a pinched nerve and safety Tom Flynn has a foot injury. Oklahoma at Nebraska
