It's hard to believe a physical specimen who rushed for thousands of yards in college football and even made the Pro Bowl in the NFL could be affected by heart disease.

But that's exactly what happened to Michigan State great Lorenzo White.

The 48-year-old went to the doctor not long after the Spartans won the Rose Bowl on Jan. 1, and the diagnosis was shocking: Congestive heart failure.

"I didn't know what was going on," White said Tuesday on Mad Dog in the Morning. "I just had a pain in my stomach."

White said he was admitted to the emergency room, where his pulse was recorded at over 200 beats per minute.

He's doing "a lot better" now, though, he said. White has lost 40 pounds in the two or three months since his health scare.

Hear him tell the full story, as well as his thoughts on Spartan football, in the complete interview below.
