A week after the Buffalo Bills’ Damar Hamlin’s heart stopped on the field and he had to be resuscitated, the football player has been released from the hospital in Cincinnati to a Boston facility.

In a tweet, Hamlin thanked the public for their support.

“Watching the world come together around me on Sunday was truly an amazing feeling,” he wrote. “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!”

While it’s too early to know what caused Hamlin’s cardiac arrest, doctors are expected to do more tests in the upcoming days.
