Here are the latest developments:

• Hamlin has made “a fairly remarkable recovery”: Though Hamlin remains in intensive care, he is demonstrating “good neurologic recovery” and is awake and holding hands with family in the hospital, Pritts said Thursday.

• He has a long way to go: “This marks a really good turning point in his ongoing care,” Pritts said, but “there are many, many steps still ahead of him.” Hamlin’s next big milestone will be breathing on his own without a ventilator, said Dr. William Knight, director of emergency medicine.

• Cardiac arrest cause still unknown: Tests are underway to determine the cause of his cardiac arrest, Knight said. Cardiac arrest results from electrical disturbances that cause the heart to suddenly stop beating properly, and death can occur quickly if help isn’t rendered immediately; it is not the same as a heart attack or heart failure.

• Hamlin lost pulse on the field: While surrounded by medical teams on the field, Hamlin lost his pulse and had to be administered CPR and defibrillation as fans and teammates looked on, Knight said. He was then intubated in the ambulance and arrived at the hospital about 30 to 45 minutes after he collapsed, the doctor added.

• Bills are back to work: The team met Wednesday and held its first full practice of the week Thursday in preparation for hosting the Patriots on Sunday. The team has been receiving “incremental updates” from medical staff as well as from Bills general manager Brandon Beane and head athletic trainer Nate Breske who stayed behind in Cincinnati, head coach Sean McDermott said. “I think the fact that we just keep hearing good news about Damar, it just keeps pushing us forward,” quarterback Josh Allen told reporters Thursday.

• “People are going to be changed forever”: The players have had “some very open and honest and deep talks” since their teammate was hospitalized Monday, Allen said. “I think putting that helmet back on was a really good thing for our team,” he said of returning to practice, “… but I would be lying to you if I didn’t say, some people are going to be changed forever after being on the field and witnessing that and feeling those emotions.”
