Forum:Wyvern vs Doomcaliber

No offense to anyone, but i would only like an answer from a recognized Name on this site. If i don't know you i will just ask for a more recognized person to answer as well.

Okay so my opponent has Doomcaliber Knight in atack mode on his side of the field and i have Red-Eyes Wyvern in my grave.

I activate Red Eyes Wyvern's effect and doomcaliber is forced to negate it. Can i activate it again in the same end phase or is Red Eyes Wyvern already removed for a the cost?
