Steph Curry stared death in the eye once again -- with the NBA superstar finally getting his sparring rematch against Canelo Alvarez ... and shock, shock -- it ended in a big, fat L!!
Remember, Curry first faced off against the boxing champ a year ago -- when he playfully squared up with Alvarez at the celeb American Century Championship tournament in Lake Tahoe.
33-year-old Curry narrowly escaped catastrophe in their initial encounter, and the dude never got over it ... 'cause when he peeped Canelo at the Edgewood Tahoe resort on Wednesday, it was ON!
