It's one of the most celebrated rivalries in the country - Ohio versus Michigan. So when a young diehard "Buckeye" was diagnosed with a brain tumor, he took the grit and determination that is that grudge match, and named his tumor "Michigan."

Who would you bet on?

It makes sense that Grant Reed would be a diehard Buckeye. His mom and dad met while they were in the Ohio State marching band together. So when the 13 year-old was diagnosed with a brain tumor two years ago he took the grit and determination that are hallmarks of that epic grudge match and named his disease "Michigan."

If you were betting on "Michigan" you lost...Grant creamed it!

See the brave young Buckeye's story below.
