"Yes, it is (true)," said Charles. "He has asked for his release. He wants to go to a different pasture."
Green, a native of North Babylon, N.Y., averaged 7.8 points and 5.0 rebounds in 21.3 minutes during his freshman season.
Charles does not have a sense of where Green will wind up.
"I respect (Manhattan coach Barry Rohrssen)," said Charles. "I haven't really talked to other people about it yet because I wasn't sure that Rashad would go through with this. I think the other day he made it clear to Barry that he wanted to transfer. I guess at this point we'll have to start looking at some other options."
Charles believes that the decision was based on playing time.
"I think there are a lot of guards in that program," said Charles. "He just felt like he wouldn't get the amount of playing time he wanted."
Green played his high school ball at St. Mary's in Manhasset, N.Y. He did a post-graduate stint at Bridgton Academy (Maine) last year.
Green's older brother, Danny, is a junior at North Carolina.
