Keith Thurman TKO after third round Julio Diaz live round-by-round update

Apr will do live round-by-round updates of tonight's welterweight bout during which Keith "One Time" Thurman scored a second-round knockdown on the way to a third-round technical knockout victory over two-time lightweight titlewinner Julio Diaz, whose corner stopped the fight due to a rib injury before the fourth round at the StubHub Center in Carson, Calif.

The 25-year-old Thurman (23-0, 21 knockouts) scored his third straight stoppage win against the 34-year-old Diaz (40-10-1, 29 KOs).

In his previous fight, Thurman scored knockdowns in the fifth and final rounds of a ninth-round technical stoppage victory over Jesus Soto Karass in December. Prior to Soto Karass, Thurman scored a 10th-round knockout of previously unbeaten Argentine Diego Chaves, whom he dropped once each in the ninth and final rounds to end the loser's streak of five consecutive stoppage wins last July.

Diaz is 0-3-1 in his past four fights, but three of those bouts were a draw and a unanimous decision loss against unbeaten current IBF welterweight beltholder Shawn Porter and a close decision setback to former 140-pound titleholder Amir Khan.
