Jacksonville Jaguars left tackle Cam Robinson is facing a suspension for violating the NFL's performance-enhancing drug policy, according to a source.

The NFL is awaiting the results of Robinson's B sample before deciding on the length of the potential suspension.

This would be Robinson's first offense, and he could be suspended for two, six or eight games depending on which prohibited substance was found.

Robinson, who is entering the second season of a three-year, $52.75 million contract extension he signed in May, missed the final three games of the 2022 regular season and both Jaguars playoff games after suffering a knee injury.

Four players on the Detroit Lions have received suspensions from the NFL for violating the league's gambling policy.

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

Jameson Williams, a 2022 first round pick by the Lions, received a six-game suspension. Stanley Berryhill also has been suspended for six games. These two did not bet on NFL games, the team said. The Lions traded up to get Williams at No. 12 in the 2022 draft.

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.
