Defensive back Josh Shaw hasn't been around the Cardinals much after going on injured reserve in late August with a shoulder issue. His future with the team was tenuous anyway after signing a one-year contract last offseason and the development of young defensive backs like Byron Murphy, Deionte Thompson and Jalen Thompson.

But his Arizona future was sealed Friday, when the NFL announced Shaw was suspended indefinitely -- at least through the end of the 2020 season -- for betting on multiple NFL games on multiple occasions this season.

The NFL investigation uncovered no evidence that Shaw got any inside information, or that any games were compromised. There was also no evidence that any Cardinals players or coaches or other NFL players knew what Shaw was doing.

"The continued success of the NFL depends directly on each of us doing everything necessary to safeguard the integrity of the game and the reputations of all who participate in the league," NFL commissioner Roger Goodell said in a statement. "At the core of this responsibility is the longstanding principle that betting on NFL games, or on any element of a game, puts at risk the integrity of the game, damages public confidence in the NFL, and is forbidden under all circumstances. If you work in the NFL in any capacity, you may not bet on NFL football."

Shaw, who was suspended in college at USC after lying about why he jumped from a balcony and hurt himself, nevertheless became a fourth-round pick of the Bengals in 2015. He can petition to get back into the league no sooner than Feb. 15, 2021, although he is still eligible to appeal his suspension.

UPDATE: Ian Rapoport tweeted that Shaw hasn't been around the team and went to a casino in the fall with friends, misunderstanding what the rules were.
