is one piece episode 744 filler?

Luffy is sent flying through Dressrosa's coastline by Admiral Fujitora's gravity wave, and upon Cavendish's orders he is grabbed by Hajrudin. Cavendish orders Hajrudin to take Luffy to the port, and Luffy unsuccessfully tries to escape from the giant's grasp and get back to his battle.

Zoro prepares to have his turn fighting Fujitora, but Bartolomeo stops him, saying they have another arrangement. The Straw Hats, samurai, and Corrida Colosseum gladiators rush onto the coast, and Usopp wonders how they could have docked all their ships there.
