That is just the crack that you CAN see with your naked eyes.
I would venture out on a limb here to say there may be more to it that you CAN'T see.
Like the gentlemen above suggested, send it to a prop shop, have it X-Rayed.
Then, they will give you an estimate for repairing it (IF it can be repaired).
Or, toss it under your bow with the anchor for a spare to be used only in emergencies to get you home.
