The Bills weren’t the only ones confused about why Kelvin Benjamin‘s touchdown was overturned on replay Sunday. The officials on the field didn’t know why the call was changed, either.

A video from Sunday’s game shows Bills quarterback Tyrod Taylor and coach Sean McDermott both talking to the officials on the sideline, seeking an explanation for why the ruling on the field of a touchdown was reversed to incomplete. But that change was made by the league’s head of officiating, Al Riveron, and the officials in the stadium couldn’t explain what Riveron was thinking.

“That’s a hell of a throw, and a catch, I thought,” deep judge Mark Hittner told Taylor.
