New York Mets pitcher Matt Harvey will make his Opening Day start after all, now that he no longer has blood clots in his bladder.

Just what was ailing Harvey was the stuff of rampant Internet concern and speculation, with the team and Harvey mum on details. On Tuesday, the New York Daily News broke the news that Harvey had passed the blood clots. Harvey, beat writer Kristie Ackert tweeted, “walked in [to the team’s facility] with a hospital wrist bracelet on. [He] looked tired and pale.” Citing an unnamed source, Ackert reported that “the blood clots are gone” and Harvey underwent an outpatient procedure Tuesday morning that showed his bladder was clear of any growths or other issues.

The lesson to be learned? Go to the bathroom when you have to go; listen up, kids. Harvey’s problem was caused, he told reporters, by “holding in my urine too long instead of using the restroom.” The initial problem was a bladder infection and blood in his urine.

Ackert added that Harvey is back on for his Opening Day start Sunday against the Royals in Kansas City.

The Mets were cryptic about Harvey’s ailment on Monday. “It’s a non-baseball medical issue we have to address,” General Manager Sandy Alderson said in Jupiter, Fla.

“It came up this morning, as far as I know, and there will be some follow-up tests and consultations that will take place over the next couple of days,” Alderson told reporters, adding, “I think it’s a little too early to attach any level of concern.”
