Joseph Randle was cut by the Dallas Cowboys on Nov. 3 after he showed signs of mental instability and he also had been involved in placing bets on sporting events during the 2015 season.

"All of that became apparent to us right during the season," Jerry Jones said last week from a Senior Bowl practice in Mobile, Ala. "Not before the season. It became real acute, a combination of things. Some issues ... became more apparent."

Jones was asked if any evidence showed that Randle bet on any NFL games.

"At this time, no," Jones said.

There's no evidence that shows Randle compromised any Cowboys' games last season, according to Jones.

"Not to my knowledge, not in any way," Jones added.
