This was the footage that I shot and was used by CBS Sports before the Denver Broncos/Pittsburgh Steelers AFC Wildcard game on 1/8/12.
Clark couldn't play in that game in Denver Colorado because of his sickle cell trait and the one mile high elevation. Back in 2009 Clark played a game in Denver and then after the game became incredibly sick. He had to have his spleen and galbladder removed in an emergency surgery. So the Steelers head coach wouldn't allow him play this time around.
As the game didn't turn out well for the Steelers and their defense, him missing that game turned out to be a big deal.
Shot using Canon 7D, Canon 24-70 f2.8L, sound was recorded on a Sound Devices 552 mixer with built in .WAV file recorder.
