The union representing striking professors at 14 Pennsylvania state universities says it has reached a tentative contract agreement and is ending its walkout, now in a third day.
The strike had disrupted classes for over 100,000 students.
Professors walked off the job Wednesday after the union turned down what the university said was its last contract offer.
Union spokeswoman Kathryn Morton said Friday it had made concessions on salary and benefits in return for the university system withdrawing proposed contract changes faculty had opposed.
The union represents more than 5,000 faculty and coaches.
It was the first strike in the system's 34-year history.
