Andy Reid's son Britt Reid is no longer a member of the K.C. Chiefs coaching staff, this just days after he was involved in a car crash that critically injured a 5-year-old.
35-year-old Britt -- who was a linebackers coach with the Chiefs -- was initially placed on leave after Thursday's accident ... and now ESPN reports his contract has since expired and the team did not make an effort to renew it.
In other words, he's out.
As we previously reported, cops say Reid admitted to drinking alcohol and taking Adderall allegedly smashing into 2 parked cars that were pulled over on the side of a highway on-ramp.
