Today we nearly said goodbye to Steph Curry's face ... the NBA superstar decided it was a good idea to spar with Canelo on a golf course -- and it nearly cost him his forehead!
The hilarious/terrifying scene all went down at the Edgewood Tahoe resort in Lake Tahoe on Thursday ... when Canelo and Steph were getting in a practice round for this weekend's famous celeb American Century Championship tournament.
For some reason ... Curry decided to get in a little boxing lesson with Alvarez on one of the tee boxes -- and, spoiler alert, it did not go well for the hooper.
