CLEVELAND — Marlon Byrd’s second strike with performance-enhancing drugs cost him a full season — and maybe his career.

The Indians’ veteran outfielder was suspended 162 games without pay by Major League Baseball on Wednesday after testing positive for Ipamorelin, a growth hormone releasing peptide. Byrd said in a statement he won’t appeal.

“When I learned that I had tested positive for Ipamorelin, I retained the services of private counsel and an independent chemist to determine the origin of the Ipamorelin test result because I never knowingly ingested Ipamorelin,” Byrd said. “After an extensive investigation by my lawyers and an independent chemist, it was concluded that the most likely source of Ipamorelin was a tainted supplement.

“I alone am responsible for what I put in my body, and therefore, I have decided for forgo my right to an appeal in this matter and accept the suspension,” he added. “I apologize for any harm this has caused the Cleveland Indians, Indians’ fans, my teammates, and most importantly, my family.”

It’s Byrd’s second violation of Major League Baseball’s Joint Drug Prevention and Treatment Program. Shortly after he was released in 2012 by Boston, Byrd served a 50-game suspension for testing positive for Tamoxifen.
