Aljamain Sterling's nine-fight winning streak and his run as UFC bantamweight champion came to a sudden end Saturday when Sean O'Malley knocked him out in the second round with a crushing counter right hand and some ground and pound.
Sterling threw a left that O'Malley dodged and then threw a blistering straight right that landed on Sterling's chin. Sterling went down in the center of the Octagon and O'Malley landed punches from the top until referee Marc Goddard stopped it 51 seconds into Round 2. The win, in the main event of UFC 292 at TD Garden in Boston, came after a slow-paced first round.
