Edwards remains a prominent figure at Nike, reportedly touted as a frontrunner to succeed chairman, president and chief executive Mark Parker to lead the company.
According to the Wall Street Journal an internal memo which informing staff of Edward's retirement included reports of "behavior occurring within our organization that do not reflect our core values of inclusivity, respect and empowerment", though there was nothing linking this to Edwards.
Nike Inc. said it had received complaints about inappropriate workplace behavior and that its No. 2 executive has resigned, setting off a management shuffle at the sportswear giant.
The spokesman said there were "no direct allegations of misconduct against Trevor Edwards", who carried the title "brand president". "Trevor has chose to retire", says Mark Parker.

A cold snap dubbed the "mini beast from the east " is set to arrive this weekend, with temperatures tumbling. But he added that the cold snap will be short lived, with temperatures rising "fairly rapidly" from Tuesday.
Nike said Edwards will be an advisor to Parker, until he retires in August.
"This has been a very hard time", it quoted Parker as saying.
