Kansas City Chiefs safety Tyrann Mathieu revealed he fractured his thumb during Sunday's win over the Washington Football Team in a since-deleted tweet, per Adam Teicher of ESPN.
Mathieu has mostly been able to avoid injuries in his career, appearing in 63 of 64 possible regular-season games over the past four seasons. His only absence came when the Chiefs rested their star names in Week 17 of the 2020 campaign.
The 29-year-old was placed on the reserve/COVID-19 list ahead of the season opener against the Cleveland Browns, but he returned in time for Week 2.
