Chicago Bull's Jimmy Butler sprained his knee last night when his side faced the Denver Nuggets. 

The fact that Butler sprained his knee, is not unusual in the NBA. What happened afterwards certainly is. 

Butler was fouled in the process of falling to the ground. As he was being helped into a wheelchair, the 26-year-old was informed that he had a free-throw to take. 

Without hesitation, Butler hobbled to the free-throw line to calmly score the basket before leaving the court. It was later revealed that the Bulls star is to undergo an MRI scan this morning to find out the severity of his injury.
