Overview
- The Chiefs signed R Mason Thomas on Thursday, May 21, to a four-year rookie contract reported at about $12.2–12.3 million.
- Spotrac and OverTheCap estimates place Thomas’s signing bonus near $5.3 million and show the deal is fully guaranteed, reflecting a growing market for higher second-round picks.
- Thomas’s signing brings the total of signed second-rounders to about 26 of 32, easing the risk of a repeat of last year’s protracted holdouts that kept rookies off the field.
- Kansas City still needs to sign first-round picks Mansoor Delane and Peter Woods, and Delane’s roughly $7.6 million 2026 cap charge plus Woods’ estimated $3.3 million figure may require roster or cap moves.
- Coaches expect Thomas to develop into a starter opposite George Karlaftis after a productive college career and a 4.67-second 40-yard dash, and veteran Travis Kelce has publicly praised his athleticism.
