 The ACLU is defending their case. Melanie Brown, TSN News. A sexual assault lawsuit filed against Dallas Cowboys quarterback Dak Prescott has been thrown out. A woman claimed Prescott assaulted her back in 2017 and filed suit against him. Prescott denied the claims and his attorney, Levi McCathern, called it a case of extortion. He felt like he was backed in a corner. I don't think he ever wants to see criminal charges brought against him.
