Juvia and Lucy vs. Vidaldus had no Gray in it, except a little love rival in her mind, while she was being controlled by Succubus.

In the KotSS arc she and Gajeel defeated that cube guy without Gray even being mentioned.

And then there is the confrontation with Freed during the fighting games, but that can hardly be called a fight.
