The two traded lots of verbal blows at one another in the time leading up to the bout, and many expected fireworks, with the UFC treating it as big as the two title fights on the card.

But all Masvidal needed was to run at Askren and throw a knee, dropping Askren out cold.

Askren was transported to a local hospital, according to ESPN’s Brett Okamoto.
