Volquez said he used the medication in an effort to start a family with his wife.
"As a result, I tested positive when I reported to spring training," he said. "Although I understand that I must accept responsibility for this mistake and have chosen not to challenge my suspension, I want to assure everyone that this was an isolated incident involving my genuine effort to treat a common medical issue.
Volquez, an All-Star in 2008, is already on the disabled list recovering from shoulder surgery and will be allowed to serve the suspension while on the DL. Either way, not what you want to hear if you're a Reds fan.
