Coach Jason Garrett and owner Jerry Jones remain shocked and saddened by the situation because of the type of player they thought Hurd to be.
Hurd played five years with the Cowboys before signing with the Bears this summer. He was released by the Bears after his arrest last week.
"Any time we have any player, family friend or friends that are like family that have an issue, then I worry," Jones said. "Obviously, I don't know any facts. I know the quality of person I thought and know Sam to be. So having said that, that is all I can give you. I can tell you there wasn't anybody anywhere including our league reps or anybody they knew that had any inkling about this until his arrest."
There were initial reports that Hurd had a list of NFL players as his clients, which could potentially impact the Cowboys considering how close Hurd was to his former teammates. Hurd's agent said there is no truth to that.
"I don't know any detail other than what (the agent) said in that there is no list," Jones said. "He said there is no list. Sam said that. Other than that, I don't know any detail."
Asked if he planned to amp up the background checks done by his own security team, Jones said there was really nothing more he can do. He said the team's and the league's investigations are already comprehensive.
"I can't tell you how thorough we are," Jones said. "We are very thorough. We are extremely thorough. I am satisfied we are extremely thorough. I do have first-hand input to know how the league does it and what we do as a team. This doesn't make me wonder about our thoroughness."
