This is the kind of changing injury update that drives New York Yankees fans crazy.

Paul Goldschmidt, the 37-year-old first baseman and former National League MVP, was expected to return to action Wednesday after leaving Monday’s game with a back issue.

Instead, according to the New York Post’s Greg Joyce, Yankees manager Aaron Boone made a concerning adjustment.

Goldschmidt’s return has been delayed until Friday if he gets through baseball activities without issue on Thursday.

That adds another layer of uncertainty and suspicion to an already injury-plagued spring training.

Given the Yankees’ recent injury history, even the most minor setbacks feel like red flags.

Goldschmidt left Monday’s game after just three innings and told reporters he had no concerns about missing Opening Day. Now, his return to spring training games is set for just six days before the Yankees open the season against the Milwaukee Brewers at Yankee Stadium.

Goldschmidt’s back issue may not seem like a major concern yet, but at 37, any lingering injury is worth monitoring. The Yankees acquired him this offseason, hoping he’d provide offensively and defensive stability in the lineup. While there’s still time for him to be ready for Opening Day, back problems are tricky-especially for older players.

And let’s be honest, the Yankees haven’t had the best luck when it comes to injuries.

Gerrit Cole is already out for the season after undergoing Tommy John surgery. Luis Gil is sidelined for months with a lat strain. Clarke Schmidt might be headed to the injured list with a sore shoulder. Carlos Rodón remains a question mark. And that’s just the pitching staff.

Now, their starting first baseman is dealing with a back issue.

The Yankees need Goldschmidt to be a key piece of their offense. If the back issue lingers or, worse, becomes a recurring problem, it could be a serious blow to a lineup that is already missing Giancarlo Stanton, who is battling tendinitis in both elbows.

For now, Boone and the Yankees are downplaying the concern. But if Friday comes and goes without Goldschmidt back in the lineup, the alarm bells in the Bronx will start ringing a little louder.
