Johnny Manziel's grandfather is most definitely not a fan of his ex-girlfriend, Colleen Crowley.

Has Johnny Manziel's Girlfriend Colleen Crowley Gone Into Hiding?

Following allegations of a shocking assault, which reportedly left Crowley with a ruptured ear drum, the grandfather of the Cleveland Browns' quarterback spoke out, revealing Crowley, in addition to Manziel, has "problems."

"The girl has her problems," Norman Paul Manziel said in an interview with Daily Mail Online on Tuesday. "I'm not saying Johnny's troubles are all caused by her, but … Everyone just needs to leave the boy alone. He needs his privacy right now. If he was left alone, he'd be all right. But he can't sit down without being bothered."

"His privacy starts where your nose ends," Manziel Sr. added. "He's not public property. He doesn't owe anybody anything."

Manziel Sr. isn't the first person to spotlight Crowley's alleged issues. Last week, NFL pro Deion Sanders weighed in on the situation, claiming Crowley had crippled Manziel's career.

"Johnny's in love. And Johnny's in love with something that's crippling him right now," Sanders told the Cleveland Plain Dealer. "I understand it. And it upsets me that grownups don’t understand it. Because he feels as though this game don’t love him, the people in this game don’t love him, so the only thing that he associates with love is that thing that’s really inflicting a lot of pain on him and that’s his girlfriend."
