Kemp was re-signed by Kansas City on Wednesday, Adam Teicher of ESPN.com reports.
Kemp was cut by the Chiefs on Tuesday, but he'll return to the team after Tyrann Mathieu (undisclosed) was placed on the reserve/COVID-19 list Wednesday. The 26-year-old receiver appeared in 11 games with the Chiefs and Dolphins last year and hauled in his lone target for 11 yards.
