Actually, there are 2. One takes place beside the returner at the 25 second mark at the 25 yard line, the 2nd is just ahead of him as he is cutting back at the 27 second mark at the 12 yard line. Not sure if either of those is the one called, but both are pretty easy to spot on the video provided by ai1015 and took place near the runner.Watched about 5 times. Where was the block in the back
