The Botswana National Olympic Committee (BNOC) has set up a commission to investigate a crash involving two athletes.
Baboloki Thebe was driving the car and Onkabetse Nkobolo, who was a passenger, was hospitalised.
Mmegi Online has since reported that Thebe has been fined for reckless driving by the authorities.
BNOC chief executive Tuelo Serufho told the publication that hospital fees would be paid for by the Botswana Motor Vehicle Accident Fund, while a commission is investigating the circumstances of the accident.
"It is early for me to comment on the matter because the findings of the commission would give us direction", Serufho said.
"As we speak I do not want to preempt the investigations."
Thebe won a silver medal in the 400 metres at the Nanjing 2014 Youth Olympic Games, was the African champion in 2018 and finished fourth in the same event at the 2015 World Championships.
Nkobolo, who underwent surgery following the crash, is a team-mate in Botswana's 4x400m relay team.
Both athletes won a gold medal in the event at the 2018 Commonwealth Games.
The Botswana Athletics Association is also investigating, with the athletes having been staying in a team hotel at the time of the incident.
