Street, who will not participate in Spring Training games in the beginning because of tightness in his right shoulder, said there was no wrongdoing during his treatments with Galea.
"I was notified by my agents that I may or may not be asked questions, whether that's from the U.S. Attorney's Office or the [MLB] Commissioner's Office," Street said. "Whatever that procedure entails, obviously I'm going to be ready to cooperate if and when that's necessary to answer any questions they might have.
"I really don't know the specifics of why he is in trouble, why he is not in trouble. I know that everything we had talked about that we had discussed, that we were going to do procedurally, was 100 percent within the law. We went to him because he's been very good with getting injuries healed. We'll just see whatever they need."
Galea faces charges in Canada of conspiring to smuggle human growth hormone and Actovegin into the U.S., conspiracy to smuggle prohibited goods into Canada, unlawfully selling Actovegin and smuggling goods into Canada. According to medical experts, Actovegin, de-protenized calf blood, has legitimate medical uses but has potential as an illegal performance-enhancing drug. HGH also has legitimate medical uses, but not as a performance-enhancer.
The New York Daily News has reported Galea has adamantly denied providing HGH to the athletes he treats.
Street said the 2007 treatments consisted of oxygen therapy and manual therapy, "just a therapist with their hands on me." His main reason for sticking with Galea is his ability to pinpoint injuries and their causes.
"Ninety-nine percent of all injury is diagnosis," Street said. "That's where that trust comes from. You want to get diagnosed correctly."
Of his current shoulder injury, Street said it's normal tightness. It has improved after playing catch the last two days. Not being scheduled for games initially is merely "precautionary," he said.
"We worked through two of these last spring," said Street, who joined the Rockies in a trade last season and converted 35-of-37 save chances last season. "This is pretty common for me at the beginning of the year."
