NEW YORK, New York -- Jeremy Piven is ending his run in Broadway's "Speed-the-Plow," due to a condition caused by a high mercury count, according to Variety.

The "Entourage" star missed a Tuesday evening performance and a Wednesday matinee due to his high mercury count health concerns, but David Mamet, the playwright of "Speed-the-Plow," appears skeptical of the actor's exit.

"I talked to Jeremy on the phone, and he told me that he discovered that he had a very high level of mercury," Mamet told the entertainment trade mag. "So my understanding is that he is leaving show business to pursue a career as a thermometer."

But, the show will go on said Mamet.

"The good news is that some really great actors will be helping out and stepping in, which to me is a sign of great heroism and friendship," the playwright added, but declined to name who would be stepping for Piven.

A rep for Piven told Variety that the actor wanted to continue his Broadway stint, but was advised by a team of doctors to end his run immediately.

Piven is best known for his role on "Entourage," playing manic Hollywood agent Ari Gold.

That's a great line from Mamet.

I know a couple people who have met Jeremy Piven and they all confirm that he is a giant asshole. Despite knowing this, I can't help having a massive crush on him. I have thought he was hot ever since he was on Ellen. I feel kinda dirty for liking him, but some things can't be helped.

I love him, even when he plays the slacker best friend opposite John Cusack. I have also heard he's a jerk though.
