is one piece episode 972 filler?

To the disappointment of Kaidou, King and Queen, Oden and his retainers fought strongly against Kaidou's men, even having Shinobu join them. Kaidou decided to intervene personally with his "Bolo Breath" attack, but Oden remained unharmed by the attack.

The two fought each other one-on-one while Oden's retainers battled King and Queen. Kaidou got the upper hand, knocking Oden into the fiery ground below.

Oden got up, ready to face him again. He coated his swords with Ryuo and leaps toward Kaidou.
