Johnny Manziel's family is concerned about the well-being of the troubled quarterback after he twice declined admittance to rehab facilities in the past week.

"I truly believe if they can't get him help, he won't live to see his 24th birthday," Paul Manziel told Kate Hairopoulos of The Dallas Morning News.

The family tried to convince Johnny to go to the Enterhealth Ranch addiction facility in Van Alstyne, Texas, on Saturday, but he refused to stay, Paul said. That attempt came a day after Johnny's ex-girlfriend alleged in a police report that he struck her several times, and threatened to kill her and himself.

Police said he has not been charged and the case is closed.

Paul said he tried again Tuesday to have Johnny admitted to Carrollton Springs Hospital, and told a Denton County Sheriff officer that he believed his son was suicidal. Johnny was allowed to leave the hospital, which Paul said he was upset about.

Johnny appeared to be turning a corner after spending 10 weeks in rehab last offseason, but has dealt with several high-profile off-field issues over the past few months.

In a statement released Friday, his agent, Erik Burkhardt, announced he has cut ties with his client, citing a lack of accountability from the quarterback.
