Two-time Pro Bowl defensive back Vontae Davis died this week at the age of 35.

His brother, ex-NFL tight end Vernon Davis, spoke about his brother's death in an interview with the Daily Mail.

Police say no foul play is suspected, and Vernon said Vontae "never showed a history" of drug use.

"This thing definitely caught me by surprise. I just don't know what to make of it," Vernon told the Daily Mail. "I'm leaning on the detectives to figure it out, but, right now, we have no answers. 

"They are going to run tests, and they said they'll get back to us. It could be as long as a month, a month and a half, until we know anything."

Vontae was previously diagnosed with attention-deficit disorder. 

"Maybe that's the case, maybe it's not," Vernon said on whether it played a role in Vontae's death. 

"We don't really have an answer to that because there is no way to see into our brain while we live. I was at his house two weeks ago, and he had the massage therapist there. He had a stretch therapist, a chiropractor, you name it.
