is bleach episode 273 filler?

Outside the walls of Las Noches, Yammy, Rukia, Renji, and Chad all sense the disappearance of Ulquiorra Cifer's Reiryoku. Ichigo Kurosaki's friends wonder if he had won, but Yammy punches through the wall in anger as he realizes Ulquiorra was defeated, as he had intended to go help him after he was finished with the three.

He tells the trio that they are no match for him, since he has been increasing his Reiatsu during the past few days by eating and sleeping a lot. Chad notices that Yammy grew larger as he speaks and Chad remembers that he was near Human size when he first came to Karakura Town.
