The NFL has been left with a referee shortage for the second straight off-season after two more departures from its officiating crew were confirmed.
Twelve officials have retired or left the NFL since the end of last season, the highest number since 14 left in 2013, with Mike Weatherford and Mike Dolce the latest to depart, according to Football Zebras. The reasons for their exits have not been disclosed.
The NFL has already hired 12 new officials, meaning there will be new faces on several officiating crews when the new season begins in September.
