College GameDay has descended on Happy Valley for No. 22 Auburn at No. 10 Penn State. The primetime clash will be Penn State’s annual White Out game.

ESPN has announced the guest picker for GameDay and it’s a Penn State legend. New York Giants running back Saquon Barkley will be on hand with the crew.

In 2018, Barkley was selected to the Pro Bowl as a rookie. Barkley was also selected as the NFL Offensive Rookie of the Year after setting a record for most receptions by a rookie running back in a season. Barkley was a consensus All-American and the Paul Hornung Award winner in 2017 while at Penn State.

The all-time series between Penn State and Auburn is tied at 1. The last meeting was a 13-9 Auburn victory in 2003 at the Capital One Bowl.

Penn State-Auburn is slated for Sept. 18 (7:30 p.m. EST) and will be televised on ABC.
