During an appearance on SiriusXM's Heart to Heart, NFL Players Association Medical Director Thom Mayer commented on the playing future of Damar Hamlin.

In response to a caller who asked whether Hamlin will ever play again, Mayer said this: "I don't want to get into HIPAA issues, but I guarantee you that Damar Hamlin will play professional football again."

It marks the first time anyone has suggested Hamlin will play again after suffering a cardiac arrest on Jan. 2.
