But family members said Tuesday he's in stable condition and they are anxious to see his health improve.
"He's still in a tremendous amount of pain and he's heavily medicated," said his brother, Phil Johnson.
Johnson, 47, of Yucaipa has been hospitalized at Loma Linda University Medical Center since the Jan. 21 shooting at Seccomb Lake Park.
The coach told police he left the north end of San Bernardino to go to Costco on the south end, but stopped at the park because he urgently needed to use the restroom.
He was confronted by a gunman at the park who demanded his wallet and then shot him several times, police said.
No suspects have been identified or arrested.
Phil Johnson, a 36-year-old Northern California resident, said colleagues, friends and former athletes who Johnson coached, have sent cards and came to visit him in the hospital.
"This has been amazing to see how many lives he's touched," his brother said. "It's unfortunate that something like this has to happen to bring everyone together."
But doctors have told family members that Johnson likely faces more surgery. The bullets broke bones in one arm and damaged his stomach and intestines, Johnson said.
"They're still doing X-rays to determine where the pain is coming from," he said.
