 CLEVELAND, OH - DECEMBER 13: Quarterback Johnny Manziel of the Cleveland Browns walks off the field during on December 13, 2015 game in Cleveland, Ohio. The NFL issued a statement Thursday that said, “Our review of this incident began when it happened. We are aware of the police report.” 
 
 A television station in Dallas also reported Thursday that the former Heisman Trophy winner told Colleen Crowley, “shut up or I will kill us both” after forcing her into a vehicle, hitting her and dragging her by the hair, sources told WFAA-TV/News 8. Dallas Police said in a statement later Thursday that "appropriate investigative follow-up" had been done and the case was closed: 
 
 The Dallas Police Department has conducted the appropriate investigative follow-up to the report forwarded to us by the Ft. Worth Police Department regarding an alleged incident involving Johnny Manziel. "Investigative efforts to date have not resulted in the filing of a criminal complaint and the incident is determined to be closed. No further statement is expected at this time. Crowley and Manziel spent time earlier that evening with a group of friends at the Zaza Hotel in Dallas, according to police. Sources say on Friday night, Crowley and three friends started the evening off at Victor Tangos, a swanky restaurant in the Knox-Henderson neighborhood in Dallas. Crowley told police Manziel "restrained" in some manner and "led" her down a back stairway to the valet area. "He hit me with his open hand on my left ear for jumping out of the car. Crowley did not report an assault at her apartment, and she told officers that “she was running in and out of her apartment through the front door in an attempt to get away from Jonathan.” 
 
 She told officers that she “finally rushed out of the apartment and ran to a nearby neighbor’s door to seek help.” Manziel then fled the area on foot, the report said. A Fort Worth police officer attempted to call Manziel on his cell phone but the call was not answered. This was the latest incident involving Manziel, who was also pulled over by police in Ohio in October after an altercation with Crowley while driving on an interstate. We are aware of the police report.” — Mike Leslie (@MikeLeslieWFAA) February 5, 2016 
 
 Crowley has told authorities that, according to sources, she is afraid for her safety and has drafted an order of protection to be presented to a Tarrant County district court judge. On Thursday, News 8 learned harrowing details of last week's alleged assault of Colleen Crowley by Manziel, who is currently on the Cleveland Browns roster, but is not expected to return next season. “We've been clear about expectations for our players on and off the field,” said Sashi Brown, the Browns executive vice president of football operations, in a statement Tuesday. “Johnny's continual involvement in incidents that run counter to those expectations undermines the hard work of his teammates and the reputation of our organization,” Browns statement reads. His status with our team will be addressed when permitted by league rules,” Browns executive vice president Sashi Brown said last week. The Browns on Thursday told Cleveland.com: “We're aware of the report and have nothing to add to our previous statement at this time.''
– Johnny Manziel's ex-girlfriend claims the NFL quarterback forced her into a car, hit her, dragged her by the hair, and threatened to kill them both during last weekend's altercation in Dallas. Though a police report notes Colleen Crowley "was somewhat vague on the details of the assault," sources tell WFAA that the pair—who dated for two years before breaking up in December—met in Manziel's room at Hotel ZaZa on Saturday and started arguing about another woman. Crowley told police Manziel "restrained" her then "led" her down a back stairway to the valet after she tried to leave. "I was crying and begged the valet, 'Please don't let him take me. I'm scared for my life!'" she reportedly told police. She said the valet responded: "I don't know what to do." USA Today reports Manziel told her she was too buzzed to drive, so he would take her home. Sources say Manziel—who Crowley told police seemed to be "on some kind of drugs"—drove her to her car at a local bar but dragged her back to his vehicle by her hair when she tried to hide in some bushes. "He hit me with his open hand on my left ear for jumping out of the car,” Crowley reportedly said, adding she couldn't hear two days later. Crowley claimed Manziel then threatened to kill himself, later adding, "Shut up or I'll kill us both." The altercation ended at Crowley's Fort Worth apartment where she says she grabbed a knife and Manziel fled, sources say. A police report notes Crowley became "increasingly uncooperative" during an investigation, and no charges were filed. Manziel tells TMZ that he didn't hit Crowley or threaten suicide. "It didn't happen," he says. "I'm completely stable."
