At least Nate Robinson made it to the second round.
The former NBA point guard -- who spent one season with the Boston Celtics in 2010-11 -- made his professional boxing debut Saturday against YouTube star Jake Paul on the undercard of the Mike Tyson-Roy Jones Jr. fight.
Robinson lasted until the 1:25 mark of Round 2 -- when Paul ended his night with a devastating knockout blow.
The 5-foot-9 guard-turned-boxer tweeted before the match he was "fighting for my brothers in the NBA."
But the NBA stars who tuned in to watch Saturday night weren't exactly inspired by what they saw.
Celtics teammates Jayson Tatum and Carsen Edwards, meanwhile, were more entertained by Snoop Dogg's "unique" color commentary during the Tyson-Jones main event.
The good news is that Robinson is OK despite the scary knockout -- and appears to be taking the heat in stride.
