Lyke said Wednesday that Pitt has sent the Nittany Lions a contract that would renew the series for four years starting in 2026, but has yet to hear from Penn State athletic director Sandy Barbour.
The two schools first played in 1893 and met regularly through the 2000 season. They picked it up after a layoff in 2016, and each team has won on its home field since the series picked up.
Penn State will visit Heinz Field on Sept. 8 and the Panthers will play at Beaver Stadium in September 2019, the last game in the four-game contract the two sides agreed on in 2011.
Lyke would like to keep it going, but said Pitt also can't afford to wait too long while it tries to make long-range scheduling plans.
