Translation: 
No more shaken by the demon’s mighty blows than an elephant struck with a flower garland, Lord Kṛṣṇa grabbed Cāṇūra by his arms, swung him around several times and hurled him onto the ground with great force. His clothes, hair and garland scattering, the wrestler fell down dead, like a huge festival column collapsing.
Purport: 

Śrīla Śrīdhara Svāmī explains the words indra-dhvaja as follows: “In Bengal, on the occasion of a certain festival, people erect a tall column in the form of a man and decorate it with flags, banners, etc. He [Cāṇūra] fell just as such a pole might fall.”
