A 7-year-old Indiana boy is recovering after he was run over by a golf cart and suffered a serious brain injury, according to his family.Lennon Simpson was hospitalized at Riley Children’s Hospital following the incident, which his cousin Jenny King described as a “freak accident.”

While playing in the yard with his sisters, Lennon was accidentally run over by a golf cart, according to local news station WHAS.

“It definitely was just a freak accident,” King told the outlet. “They were just being kids.”

In the days after the accident, Lennon remained unconscious as doctors treated his injuries. His family said he suffered a grade 3 diffuse axonal injury, a type of traumatic brain injury, according to a GoFundMe campaign organized by King.

On Aug. 8, King shared that Lennon had been taken off a breathing tube and was breathing on his own with oxygen.

“Lennon has a long road to recovery BUT we are making small steps to what we are praying is a full recovery!” she wrote in an update.

The following day, Lennon was still mostly in a deep sleep, but his family began seeing small signs of progress. King said he started opening his eyes for a few seconds when he was moved in his bed.

“Seeing his big brown eyes was just what my momma heart needed,” King wrote.

King said most of the trauma was to the left side of Lennon’s brain, affecting the right side of his body.

“It’s almost stroke-like symptoms,” she told WHAS. At that point, Lennon had very limited movement on his right side and could not sit up without support.

On Aug. 13, King said Lennon was showing increased awareness and had begun communicating through small signals. During speech therapy, he was able to give a thumbs-up when asked if he knew his name.

He was also able to look toward his parents and siblings when physical therapists asked him to find them by name, according to the update.

Then came another major milestone.

By Aug. 15, just eight days after the accident, Lennon had moved from the pediatric intensive care unit into inpatient rehabilitation at Riley Children’s Hospital, according to the GoFundMe.

King said Lennon’s neurosurgeon was “very impressed” by his rapid progress and told the family she had not seen that happen in a very long time, according to the family’s update on the fundraiser.
