C.J. Spillman is being investigated in connection with an alleged sexual assault at the Dallas Cowboys' hotel last month.

Police spokesperson Barry Bowling said a report was filed Sept. 20 and that the matter is still under investigation. Spillman hasn't been arrested or charged.

Spillman was signed by the Cowboys on Aug. 31 and previously was with the San Francisco 49ers.

Police say the incident occurred at the Gaylord Hotel on Sept. 20, the day before the Cowboys played at St. Louis. 

Several Cowboys players stay at the Gaylord Hotel until they find apartments, which is the case with Spillman.
