Angel Hernandez has been out of action, but it does not appear as though anything nefarious is afoot.

Baseball fans began noticing Monday that Hernandez, a controversial MLB umpire, has been out of action since April 3 and wondered what happened to him.

A source with knowledge of the situation told The Post that Hernandez has missed most of the season due to a back injury, and that he would be expected to return this season once his injury has been cleared.

“Living in this weird timeline where Ángel Hernández just stopped umpiring big league games but no one said anything about it. In most other timelines, there were retirement parties,” the Twitter account Codify Baseball wrote Monday morning in a tweet that as of 4:30 pm ET on Monday has been viewed nearly one million times.

Conspiracy theories started to pop on social media that the Cuban-born Hernandez — who has sued MLB for alleged discrimination in the past after not being assigned a World Series since 2005 and not being named a crew chief — had been shadow-retired.

Fans have often criticized Hernandez for making bad calls on the field.
