Purdue coach Danny Hope's high-scoring offense could be bolstered this week by the return of two key players - quarterback Robert Marve and running back Ralph Bolden.
Marve is trying to return four weeks after tearing the anterior cruciate ligament in his left knee. Bolden has been trying to come back from a torn ACL he sustained last season.
Getting either or both back would help boost an offense that is becoming increasingly productive.
Purdue (3-1) hosts Michigan (2-2) this Saturday.
