Johnny Gargano is set to go to war with his old partner Tomasso Ciampa ay NXT Takeover: Chicagao II in a Street Fight, but it seems their match was originally envisioned as a Last Man Standing bout.
This past Tuesday on SmackDown LIVE, Shinsuke Nakamura announced that the stipulation for his title match against AJ Styles at Money in the Bank would be Last Man Standing, and Wrestling Observer Newsletter's Dave Meltzer reckons this led to Johnny Wrestling vs. The Blackheart at Takeover being altered.
There's not really a whole lot of different between the two anyway - aside from the fact that a Street Fight can end via pinfall or submission, and the only way to win a LMS match is by keeping your opponent down for a 10 count.
