A chronological timeline of events involving Cleveland Browns quarterback Johnny Manziel since Jan. 30:

Jan. 30

Police respond to a 911 call at the Fort Worth, Texas, apartment of Colleen Crowley, whom Manziel had dated. She told police she had gotten into an argument with Manziel after the pair went out with friends the previous evening (the 29th) in Dallas. "The preliminary investigation determined that a possible assault had occurred in that jurisdiction or multiple jurisdictions," the Fort Worth police said in a statement. When Crowley told police she was worried for Manziel's safety, police dispatched a helicopter to search for him after he doesn't answer his phone. They later determined he was safe. No arrest was made because the incident took place in Dallas, but Fort Worth police said they will cooperate with Dallas police to see if a crime was committed.

The NFL said it will investigate the incident.

His status with our team will be addressed when permitted by league rules." A league source said the Browns will try to trade or release Manziel when the league year begins March 9.
