Brandon Williams, a tight end for the Colts, was taken off the field on a stretcher. Williams was blocking Broncos linebacker Deiontrez Mount, their helmets collided, and Williams took a step back and essentially fell onto the field. This was almost a mundane play that can happen on any snap in the NFL, but Williams, who suffered from spinal stenosis in college, was down on the field for a long time. It goes without saying that we hope this is not as bad as it initially looks.
UPDATE: Comparatively good news: the Colts have reported that Williams has a head injury, and has movement in his limbs.
