Callaway (knee) was waived/injured by the Chiefs on Tuesday, NFL reporter Aaron Wilson reports.
Callaway has been dealing with a bone bruise in his knee throughout the past week, and he's now been let go by Kansas City. The 24-year-old caught 43 passes for 586 yards and five touchdowns as a rookie for the Browns in 2018, but he's been unable to stick around anywhere over the past couple years due to off-field issues.
