Former Cleveland Browns wide receiver Antonio Callaway has lost his appeal and will be suspended for his next 10 games, regular season or postseason, for violating the NFL's substance-abuse policy, a source told ESPN's Adam Schefter Friday.
The Browns waived Callaway Thursday.
Callaway's agent, Malki Kawa, had tweeted that Callaway was facing the ban for taking a tainted CBD supplement.
Callaway was a healthy inactive for Sunday's win against the Bills after showing up late to a game. His replacement in the lineup, wide receiver Rashard Higgins, wound up catching the game-winning touchdown.
