Yearling buck shed or broke one side?

I had the same thing happen like 5 years ago. A yearling broke a side in October, or so I thought. When I picked the antler up, it looked exactly like a natural shed at the pedical, just as if he shed in February. He lost the other side in February and both looked like alike at the pedicels. He grew a fine and normal perfect 10 point rack the next year. I don't know what happened, but I assume it was a break from fighting and the break just happened to look like a shed I guess.
