Pro Football Hall of Famer and Dallas Cowboys legend Michael Irvin underwent testing earlier this week for throat cancer.
Irvin made the announcement in a post on Instagram on Tuesday afternoon, where he asked for people's prayers as he awaits results of a biopsy.
Irvin admitted he is scared of what the results might be. His father died from throat cancer at the age of 51.
"This demon has chased and vexed me deep in my spirit all my life. So saying I am afraid this time is a big big understatement. I AM TERRIFIED!!" Irvin wrote.
Irvin said he lost his voice celebrating the Cowboys' win over the Saints on Thursday Night Football late in the 2018 season. Video of Irvin getting fired up on the sidelines at the end of the game went viral online.
Irvin said problems with his voice lasted for nearly two months after the game, so he visited doctors and they opted to schedule a biopsy on Irvin's throat to see if there could be more serious problems.
Irvin said he would like prayers from people for him and his family.
"Could you please send up a prayer to help my family and I deal with whatever the results may be? Thanks for your thoughts and prayers in advance. I will continue to pray for your fams protection and prosperity as well. May God Bless us all," Irvin wrote.
Irvin played 12 seasons for the Cowboys as wide receiver, winning three Super Bowls as part of the famed "Triplets." He retired after the 1999 season due to an injury.
