Buffalo Bills safety Damar Hamlin’s breathing tube was removed overnight and he “continues to progress remarkably in his recovery,” the team said Friday morning, four days after the 24-year-old’s in-game cardiac arrest.

“His neurologic function remains intact and he has been able to talk to his family and care team,” it tweeted, citing physicians at the Cincinnati hospital where he’s being treated.

Buffalo Bills safety Damar Hamlin has made “substantial improvement” in a Cincinnati hospital following his in-game cardiac arrest on Monday, doctors announced Thursday, and is now awake and moving his hands and feet.

The 24-year-old can communicate by shaking his head, nodding or writing brief notes but can’t yet speak because he’s on a ventilator, Dr. Timothy Pritts, part of his medical team, told reporters. Upon awakening, Pritts said, Hamlin’s mind was still on the game as he scribbled his first question on a clipboard: “Did we win?”

“So, we know that it’s not only that the lights are on, we know that he’s home. And that it appears all cylinders are firing within his brain,” said Pritts, who is vice chair for clinical operations at University of Cincinnati Health where Hamlin is being treated.
