The Fort Worth Star-Telegram said a police "after-action" report it obtained detailed the seizure of 15 vehicles, 18 iPhones and small quantities of prescription drugs, cocaine, methamphetamine and Ecstasy.
Police made 18 arrests during the raid Feb. 15. Fifteen of the suspects were university students.
The four football players have been identified as defensive tackle D.J. Yendrey, offensive tackle Tyler Horn, safety Devin Johnson and linebacker Tanner Brock.
The raid followed an investigation in which police said officers posing as drug buyers made purchases from TCU students. Arrest warrant affidavits said about $11,000 was spent on purchases of marijuana and prescription drugs.
