During Iowa's beatdown of Purdue, it looks like refs gave the Boilermakers a little bit of a break, already down 35-7 toward the end of the first half.
Two Purdue kick returners ran into each other trying to field the kick on around the one-yard line, only to backtrack into the end zone and down the ball for a pretty clear safety.
Only officials originally called a touchback before calling the ball down on the half-yard line.
Both calls appeared to be quite incorrect.
