In a week when Ben Carson’s been criticized for encouraging would-be victims to charge at a shooter, a man who became famous for his heroism in doing exactly that is back in the news for the grimmest reason. I know what you’re thinking, but as of noon ET, there’s no reason to believe this was a jihadi reprisal. According to TMZ, Stone was stabbed while trying to protect a friend during a fight outside a bar.

“Captain America,” they call him.

The attack reportedly happened early Thursday morning in Sacramento while Stone was protecting a friend. Stone was stabbed 4 times in the chest while standing on a street corner. 

The 23-year-old U.S. airman 1st class is reportedly in stable condition.

A little more from People magazine:

Spencer Stone’s Father Brian Stone was fielding calls and tells PEOPLE he still wasn’t exactly sure of the details of what happened: “He’s out of surgery and doing well. He’s been upgraded so no longer critical and it looks like he’s going to be okay. All I can say is that this world is not short of idiots.”

According to KCRA, a fight in the street led to Stone’s being stabbed multiple times. Investigators blocked off two blocks in the area, the station reports.

Stone was a hero twice over during the train attack in August. Not only did he rush the gunman and stop him before he could shoot up the car, he saved the life of a passenger who’d already been shot and was bleeding out on the floor — and he did it after having been stabbed himself. (“I look at my thumb and it’s hanging halfway off.”) He’s an EMT by training who joined the Air Force to pay for his training and who, his father hopes, will go on to become a doctor. Here’s hoping for a speedy recovery. Stand by for updates.

Update: Police have surveillance video of the fight.
