ORCHARD PARK, N.Y. (AP) — Doctors who treated Damar Hamlin said the Bills safety was back in Buffalo on Monday, an uplifting sign of the remarkable progress he has made a week after going into cardiac arrest and having to be resuscitated on the field during a game in Cincinnati.

Hamlin tweeted Monday thanking the staff at the University of Cincinnati Medical Center and praising the doctors and nurses at his current location, Buffalo General Medical Center.

“Headed home to Buffalo today with a lot of love on my heart,” Hamlin tweeted. “Watching the world come together around me on Sunday was truly an amazing feeling. The same love you all have shown me is the same love that I plan to put back into the world n more. Bigger than football!”

Hamlin was discharged from the University of Cincinnati Medical Center in the morning and flown to Buffalo, where Dr. William Knight said he was “doing well.”

The team released a statement from the UC Medical Center on Twitter saying, “We are thrilled and proud to share that Damar Hamlin has been released from the hospital and returned to Buffalo. He is doing well and this is the next stage of his recovery.”

Hamlin’s return comes a day after he cheered on the Bills from his hospital bed during their regular season-ending 35-23 win over the New England Patriots. The game proved to be a cathartic outpouring of support for the Bills and Hamlin.

The Bills wore No. 3 Hamlin patches on their jerseys and honored their teammate by raising three fingers in the closing minutes, while tight end Dawson Knox celebrated his touchdown by forming his hands into the shape of a heart.

Hamlin responded on his Twitter account with a heart message directed toward Knox.

Fans joined in, with many holding up red hearts and No. 3 signs.

The 24-year-old Hamlin has made significant progress in his recovery since spending his first two days at the University of Cincinnati Medical Center under sedation and breathing through a ventilator.

He was awakened on Wednesday night and was eventually able to grip people’s hands. By Friday, Hamlin was able to breathe on his own and even addressed the team by videoconference, in which he told the Bills, “Love you boys.”

The latest update from doctors came on Saturday, when they described Hamlin’s neurological function as “excellent,” though he remained listed in critical condition.

On Monday, Knight and Dr. Timothy Pitts issued statements about his health through the Bills’ Twitter account.

“Damar walked his first lap around the hospital on Friday and he’s on a normal to accelerated trajectory,” Knight said via the tweet. “We continue to be ecstatic about his recovery.”

Pitts added when the Bills returned the opening kickoff for a touchdown, he was jumping up and down.

Later that day, Hamlin tweeted: “Putting love into the world comes back 3xs as much… thankful for everyone who has reached out and prayed. This will make me stronger on the road to recovery, keep praying for me!”

The NFL will show support for Hamlin during all Week 18 games by including a pregame moment of support, painting Hamlin’s No. 3 on the 30-yard line and pregame shirts with “Love for Damar 3.”

Hamlin’s heart stopped on Monday night after making what appeared to be a routine tackle in the first quarter against the Bengals. The game was initially suspended before officially being canceled later in the week.
