The Chiefs announced they re-signed receiver De'Anthony Thomas on Tuesday.
They waived receiver Davon Grayson in a corresponding move.
Thomas appeared in five games for the Chiefs last season, catching three passes for 29 yards and a touchdown. He also had a carry for 6 yards and accounted for 106 combined return yards.
He ended the season on injured reserve with a broken leg.
The Chiefs made him a fourth-round pick in 2014.
