He went on to thank Dolphins owner Stephen Ross and “players, coaches and staff for their complete cooperation throughout this process.”
Wells met last week with Martin in New York.
Martin, a second-year pro from Stanford, has said he wants to play football again. He has been with family in California undergoing treatment for emotional issues.
Incognito has said he regrets racist and profane language he used with Martin, but said it stemmed from a culture of locker room “brotherhood,” not bullying.
Wells is expected to determine the roles of coach Joe Philbin, other coaches and Miami’s front office, and the NFL has said his final report will be made public.
Ross has acknowledged that changes are needed and formed two committees to study the team’s locker room culture.
