KANSAS CITY — Britt Reid, an assistant coach for the Kansas City Chiefs and the son of head coach Andy Reid, was involved in a serious crash Thursday night, according to police. Reid is being investigated for "impairment," Kansas City police said.
Reid suffered non-life-threatening injuries, but two children in a car involved in the crash were seriously injured, including one with life-threatening injuries.
The 35-year-old is a linebackers coach for the Chiefs, who will play in the Super Bowl this Sunday against the Tampa Bay Buccaneers.
"The organization has been made aware of a multi-vehicle accident involving Outside Linebackers Coach, Britt Reid," the Chiefs said in a statement. "We are in the process of gathering information, and we will have no further comment at this time. Our thoughts and prayers are with everyone involved."
The incident took place Thursday night at about 9 p.m. near the Chiefs' practice facility at the Truman Sports Complex, according to police.
Reid hit a car that was assisting another that had run out of gas on the side of the road, causing a chain reaction that hit the stalled vehicle, according to police. A 5-year-old in the broken down car suffered life-threatening injuries, while a 4-year-old in the car suffered non-life-threatening injuries, police said.
The driver of the car Reid hit initially and two adults in the car that ran out of gas were not injured.
Kansas City NBC affiliate KSHB, which obtained a search warrant related to the case, reported Reid admitted to drinking before the crash.
The Chiefs are not traveling to Tampa, the host city for Super Bowl 55, until Saturday. The team was remaining in Kansas City due to COVID-19 protocols.
Reid remains in the hospital and will not travel to the Super Bowl, a source told ESPN's Dianna Russini. He could be hospitalized for days due to his injuries, the source added.
Reid has worked alongside his father, who has coached in the NFL since 1992 and taken the Eagles and Chiefs to the Super Bowl, since 2013. Andy Reid won his first title with Kansas City last year.
Britt Reid pleaded guilty to simple assault and flashing a gun at another driver in a road rage incident in 2007, according to Montgomery County court records, and served prison time. While in prison, he also pleaded guilty to a charge of driving under the influence of a controlled substance from a separate incident, court records show.
He was twice given tickets for speeding while working for the Chiefs -- on Aug. 19, 2014 and Aug. 9, 2018, according to court records. He paid both fines.
