The UK Sun is reporting that Ugama was released after a second wellness violation but that the real reason was for refusing to enter rehab.
The article says that Umaga was not released under the "3 strikes you are out" provision of the Wellness Program.
WWE commented to the Sun:
"As reported on WWE.com on Monday June 8 2009, WWE Superstar Umaga (Edward Fatu) has been released from his World Wrestling Entertainment contract.
"However consistent with the practice of announcing wellness policy violations, it should be noted that Umaga’s termination was due to his second violation of the WWE Wellness Program and his subsequent refusal to attend a rehabilitation facility."
