The Panthers trailed at one point 24-0. It wasn't until midway through the third quarter that Klingerman started stringing passes together, ending the night with 187 yards passing after having only 14 through the first two quarters.
Klingerman threw a nice pass to Zach Ashford to avoid the shutout and scored on a 1-yard sneak up the gut in the fourth quarter, but it was too little, too late for Bloomsburg as South Williamsport won its first playoff game since 1997 on the legs of Brandon Stonge, who ran for a team-high 222 yards and three touchdowns en route to becoming the Mounties all-time rushing leader.
