Substitutions will have several officials working out of position [live updates]

We are finding more scheduling oddities due to this week’s air travel woes.

The NFL is trying to assign officials to games where ground transportation is reasonable, while some officials are able to catch a flight in or near their game city or in the vicinity. This is going to place several officials out of position. Most notably, at least 3 referees will wear a black hat and work a different field position this weekend.

Referees Carl Cheffers and Alex Kemp are scheduled to work as umpires in games that already have another referee assigned. Referee Shawn Hochuli is slated to work as a back judge on Sunday, the position he worked when he entered the NFL.

Kemp and his crew were originally scheduled to have a week off, but all officials that were originally on a bye are available for substitution

As the day progresses, these and other assignments could change.
