Four Lions players, including former first-round pick Jameson Williams, have been suspended for violating the NFL’s gambling policy following an investigation by the league.

Lions wide receiver Quintez Cephus and safety C.J. Moore have been suspended indefinitely for betting on NFL games, as was Washington Commanders defensive end Shaka Toney. They can reapply for reinstatement after one year, though the Lions announced that their two players have been released.

Second-year wide receivers Williams and Stanley Berryhill are being suspended for six games each for mobile betting that occurred at the Lions’ Allen Park facility. They did not bet on NFL games, the Lions said.

The Lions became aware of the NFL’s investigation about a month ago before the league reached a final decision.

“As a result of an NFL investigation, it came to our attention that a few of our players had violated the league’s gambling policy,” Lions general manager Brad Holmes said in a statement. “These players exhibited decision making that is not consistent with our organizational values and violates league rules. We have made the decision to part ways with Quintez and C.J. immediately. We are disappointed by the decision making demonstrated by Stanley and Jameson and will work with both players to ensure they understand the severity of these violations and have clarity on the league rules moving forward.”

Separate from these punishments, several Lions staff members in various departments were dismissed last month for violating the gambling policy, a source told ESPN.

According to league policy, NFL players and personnel cannot bet on NFL games, the draft or any league-related activities under any circumstances. They also cannot place any bets while at a team facility or on any team-related travel.

Entering his second season, there was a ton of excitement around Williams, who was limited to six games as a rookie after recovering from a torn ACL that he suffered in the 2021 College Football Playoff championship game while playing for Alabama.

The Lions traded up to get Williams at No. 12 overall in the 2022 draft, and he flashed glimpses of his playmaking ability within a limited role, scoring a 41-yard touchdown against the Minnesota Vikings on his lone reception of his first season.

Williams recently attended throwing sessions in California with several Lions teammates and quarterback Jared Goff to develop chemistry. He was also on-site this week for the Lions’ voluntary offseason workouts.

Williams and Berryhill can participate in organized team activities, minicamp, training camp and the preseason but won’t be available for regular-season games until Week 7.

The punishment for Cephus and Moore is similar to that of Jacksonville Jaguars wide receiver Calvin Ridley. Ridley was suspended for the 2022 season over bets he made in November 2021 that included the Atlanta Falcons, whom he played for at the time. Ridley was reinstated by the NFL in March.
