The NFL has taken the highly unusual step of firing down judge Hugo Cruz for performance reasons, sources confirmed to ESPN on Thursday.
Cruz last worked in Week 6 and is no longer an NFL employee.
Cruz, who joined the NFL in 2015, was responsible for one high-profile mistake this season. He missed an obvious false start by Los Angeles Chargers left tackle Russell Okung on a scoring play in Week 6 against the Cleveland Browns. He did not work in Week 7.
Otherwise, the details of the league's decision -- including other mistakes Cruz is presumed to have made -- are unknown. An NFL spokesman declined to comment and representatives of the NFL Referees Association did not respond to a request for comment.
The news was first reported by FootballZebras.com, which tracks college and pro football officiating trends. According to the website, the NFL has never fired an official in-season during the Super Bowl era because of performance.
Sources reached by ESPN insisted there was no indication that Cruz committed an off-field mistake, nor that his firing was in any way based in discipline.
The NFL grades officials on their performance on every play of every game. The league has occasionally suspended or re-assigned officials for mistakes of game administration, but it evaluates their careers a yearly basis by placing each in one of three tiers.
Tier I is for the top performers, Tier II is for mid-level grades and Tier III is for the worst-performing officials in a given year. Historically, two consecutive seasons in the third tier makes an official vulnerable to termination.
That system is designed to prevent instant evaluations based on a single mistake or a series of closely-timed mistakes. The NFL's quick decision on Cruz will send shock waves through the officiating ranks. Officials who once could be assured that their season would be evaluated through a larger lens will now be left to wonder if they could receive a career-ending phone call after one bad game.
