Denver Broncos defensive end Derek Wolfe told 1043 The Fan that he has been experiencing numbness in his face, arms and legs over the course of the last few weeks as the result of a neck injury that forced him to exit his team’s game against the rival Oakland Raiders on Sunday.

“There’s not like one real answer to give right now because we need to run some more tests to really figure out what’s causing the numbness,” said Wolfe. “A stinger is a stinger, but when your face is going numb and then your quad is going numb, that’s when you have to make sure. Whenever the MRIs and everything, that’s all clear, that’s when you have to go check the nerves and find out what’s going on with the nerves and then you can reverse it.”
