Damar Hamlin’s injury condition appears to have taken a turn for the better. The Buffalo Bills safety’s uncle Dorrian Glenn said that Hamlin was originally on 100 percent oxygen and is now down to 50 percent, according to Matt Parrino of Syracuse.com.

“That’s a good thing. That’s a good sign,” said Glenn.

Hamlin’s uncle noted that his nephew was resuscitated both on the field and at the hospital.

Josina Anderson of CBS Sports further reported that she had heard word Hamlin’s “breathing is improving.” Mike Garafolo also reported that Hamlin’s teammates received a “guardedly optimistic update” on the safety’s status from the Bills earlier on Tuesday. Of course, it’s worth noting that the Bills star is still listed to be in critical condition.

However, given the gravity of the situation and the fact that Damar Hamlin’s life is hanging in the balance, the mere fact that his breathing is beginning to improve has to be considered a step in the right direction.

In one of the most chilling on-field scenes in NFL history, Hamlin collided with Cincinnati Bengals wide receiver Tee Higgins and was able to stand up before collapsing on the field.

Trainers from both teams rushed to his aid as players from both teams were visibly shaken by the injury. An ambulance was called onto the field, and CPR and AED were administered to the Bills defender.

Hamlin reportedly had a pulse but was not breathing on his own as he was transported to the University of Cincinnati Medical Center. After his arrival at the hospital, another update was provided, saying that the Bills safety’s vitals were back to normal and that he was intubated.

The team said on Tuesday that he had suffered cardiac arrest on the field. There has been an outpouring of support from players around the NFL, and from other sports, for Damar Hamlin.

His toy drive has raised more than $5 million and counting thanks to donations on a GoFundMe page.

More from Glenn with the NFL Network’s Cameron Wolfe: “A lot of people don’t get to see how loved they are while they’re alive, so for him to have a situation where he could have been taken away and he has a chance to come back and see all that love that he got.”
