Callaway was benched for Sunday’s game against the Bills for disciplinary reasons. Before that, he served his four-game suspension for a violation of the NFL’s substance-abuse policy before being activated last month.
The Browns elected to waive Callaway on Thursday.
Callaway, 22, is a former fourth-round pick of the Browns back in 2018. He agreed to a four-year, $3,177,856 contract that included a $717,856 signing bonus and stands to make a base salary of $570,000 for the 2019 season.
In 2019, Callaway has appeared in four games and caught eight passes for 89 yards receiving and no touchdowns.
