CLEVELAND (AP) — With Johnny Manziel’s professional career in doubt and his personal life crumbling, his father fears for the troubled quarterback’s safety. Manziel is facing a criminal investigation by police following allegations that he hit his former girlfriend last weekend in Texas. He was dropped by his agent Friday, was ordered this week to stay away from his ex for two years and will be released by the Cleveland Browns next month after two tumultuous seasons. “I truly believe if they can’t get him help, he won’t live to see his 24th birthday,” Paul Manziel told The Dallas Morning News. Manziel’s father said the family has made two unsuccessful attempts in the past week to get the player into a rehab clinic. Manziel agreed to go to the Enterhealth Ranch addiction facility in Van Alstyne, Texas, but he would not stay, Paul Manziel told the Morning News.
