Jerry Howarth, the voice of the Toronto Blue Jays has revealed he has prostate cancer. Howarth who called the Blue Jays in the ALCS told Canada’s CTV network that an MRI found the cancer after a biopsy did not find not.

Howarth will undergo surgery next week to have a small tumor removed. The Blue Jays voice is supporting a study to determine whether MRI’s are more effective in detecting cancer than other tests.

He told CTV, “I had an MRI, which I thought (stood for) magnetic resonance imaging, but I found it was really most revealing investigation.”

The Blue Jays wished Howarth well:
