Kansas City Chiefs linebackers coach Britt Reid has been suspended from the team ... as police investigate his involvement in a bad car accident that left a 5-year-old girl fighting for her life.
As we previously reported, cops say Reid admitted to consuming alcohol and Adderall before a bad 3-car crash around 9 PM Thursday night that left a child in critical condition.
The child's family members say the girl suffered major brain damage in the accident ... including swelling and internal bleeding. She has not woken up since the crash.
Reid -- who did not travel with the Chiefs to Super Bowl LV in Tampa this past weekend -- has officially been placed on administrative leave, the team announced Tuesday.
"We remain in the process of gathering information on the incident, and we will continue to assist local authorities as requested," the team said in a statement.
"Our focus remains on Ariel Young and her family. We have reached out to the family to offer our support and resources to them during this difficult time, and we will continue to pray for her recovery."
Chiefs head coach Andy Reid -- Britt's father -- also addressed the situation after the Super Bowl loss on Sunday ... saying, "My heart goes out to all those who were involved in the accident, particularly the family with the little girl who's fighting for her life."
