Attorneys for 20-year-old Praise Martin-Oguike said the charges were dismissed as jury selection was to begin Monday.
The woman told police Martin-Oguike assaulted her in May 2012 in his dorm room. Martin-Oguike said the encounter was consensual.
Martin-Oguike's attorney James Funt said charges were dropped after a review of the woman's text messages with her friends indicated she was not truthful about being raped.
Funt said the former Temple linebacker was victimized by the woman "simply because he would not agree to have a romantic long-term relationship with her."
Martin-Oguike was suspended from the team after he was charged. He now attends a New Jersey community college.
