Weidman knocked out Silva at the 1:18 mark of the second round, and in the process ended the Brazilian's 16-fight winning streak in the UFC.
It was also Silva's first loss since 2006, and the first time that he has ever been knocked out.
The loss also stopped Silva's streak of 10 consecutive successful title defenses, also a UFC record.
Weidman started off strong, but Silva was taunting and playing around in the opening round, and even putting his hands on his hips.
Silva paid for his nonchalance in the second round when, with his hands on his hips again, Weidman connected on a huge left hook that floored the Brazilian legend.
The loss dropped Silva's record to 33-5. Weidman, meanwhile, remains unbeaten in his MMA career with a 10-0 record.
