Michael Irvin's clearly SUPER relieved to find out he's cancer-free ... 'cause the Dallas Cowboys legend was still smiling from ear to ear hours after receiving the great news!!
"I appreciate the prayers!" Irv told TMZ Sports out in D.C. on Sunday night.
As we previously reported, the Hall of Fame receiver announced last week he was "terrified" he might have throat cancer after losing his voice for several months during the NFL season.
"Saying I am afraid this time is a big big understatement," Irvin wrote on his social media page.
