VIDEO: Cristiano Ronaldo accidentally kicks Lucas Biglia above the waist

Cristiano Ronaldo may not have scored in Portugal's 1-0 friendly win over Argentina on Tuesday, but he inflicted some damage on Lucas Biglia.

The closing moments of the first half saw Ronaldo challenge for the ball by raising his right foot far higher than he probably should have, resulting in Biglia falling to the ground in a considerable amount of pain.

Based on Ronaldo's reaction, the high kick was far from intentional.
