The San Antonio Express is reporting that ten-time All-NBA forward Tim Duncan had concerns about his marriage as long as a year ago and hired a private investigator to tail his wife of twelve years.

New details into Duncan’s pending divorce from wife Amy are emerging, including such revelations as Amy moved out of the family home several weeks ago, The Express also reported.

TMZ.com also reports that it was Amy who formally filed a petition for divorce on March 27, claiming their union has become “insupportable because of discord and conflict.”

Further reports claim attorney Sue M. Hall, lead counsel for Duncan, countered by requesting that the date for discovery be amended from June 13 until 30 days after the Spurs playoff run ends. San Antonio now leads Memphis 2-0 in the Western Conference Finals.

In the request to have the discovery gate delayed, T.T.D. (Duncan's middle name is Theodore) was identified as a member of the Spurs team whose "employment is currently making extraordinary demands on him and hopefully will continue to make those demands for the next 30 days or so," TMZ reported.

Duncan’s attorney also indicate his client plans to enforce a prenuptial agreement the couple signed at the time of the union, which came some four years after he was selected as the first pick in the 1997 NBA draft, according to TMZ. Just last year, Duncan inked a 3-year, $36 million extension with the team.

The couple has two small children, and seems Duncan has indicated he and his soon to be ex will come to an agreement over financial support.

Tim and Amy were college sweethearts at Wake Forest University, where he was a star on the basketball team and she was a cheerleader.
