UFC Argentina is in progress, and Johnny Walker just brutally knocked out Khalil Rountree in the opening round to make his promotional debut in style. Holy smokes! Before that, Ian Heinisch went the distance in his UFC debut tonight, using his strikes and sub attempts to pick up a unanimous decision over Cezar Ferreira.
Also on the main card, Marlon Vera overcame a rocky opening round to go on and hurt Guido Cannetti with strikes, and then finish him off with an RNC in the second. Vera has now finished his last four wins and is proving to be quite the killer at 135 pounds.
