Kiel was trying to slide feet first to the turf when he was hit up high by DB Chauncey Lanier and then had his head ricochet off the playing surface. Although a penalty flag was thrown, Lanier was not ejected for targeting after review.
Kiel was motionless for several minutes and was carted off the field. Thankfully, ESPN later reported that Kiel had feeling in all his extremities.
