Watch: Trace McSorley Injures Knee in First Half, Rips off Long Touchdown Run in Second Half

McSorley was on the bench for two series, sitting as backup Tommy Stevens went 2-4 for 27 yards.

Penn State quarterback Trace McSorley exited the Nittany Lions' matchup vs. Iowa in the second quarter on Saturday, heading to the sidelines with an injured right leg. The senior was replaced by redshirt junior Tommy Stevens, who registered two completions in four attempts. 

McSorley returned to action late in the second quarter. His pass line wasn't pretty in the first half, but he did rip off a touchdown run to kick off the second half, sprinting 51 yards to give the Nittany Lions a 24-17 lead at Beaver Stadium in University Park, PA.
