An attorney who prosecuted Centennial Olympics Park bomber Eric Rudolph—King & Spalding partner Phyllis Sumner—is now trying to help the Atlanta Falcons recover a $3.75 million signing bonus from Michael Vick.

Vick, the former Falcons quarterback who was jailed last year for bankrolling a dog-fighting ring, filed for Chapter 11 bankruptcy protection on Monday in the U.S. Bankruptcy Court for the Eastern District of Virginia. Vick said in the filing that his debts total somewhere between $10 million and $50 million.

Sumner, a litigation partner at King & Spalding in Atlanta, is listed as counsel to the Falcons in the bankruptcy papers. While an assistant U.S. Attorney in Atlanta, Sumner was involved in the prosecutions of Centennial Olympics Park bomber Rudolph and former Atlanta mayor Bill Campbell.

Sumner declined to comment on the Vick case.

In a court filing Vick’s attorneys blamed his bankruptcy filing on a suit filed against him by his former agent, Andrew Joel of Richmond, Va. In the suit Joel claims Vick reneged on an endorsement deal; Joel subsequently sued the football star for $45 million. Vick’s largest debt in his bankruptcy filing is the $4.5 million that he estimates he owes to Joel Enterprises Inc. of Richmond.

“The Debtor’s goal was to avoid bankruptcy and work out consensual resolutions with each of his creditors who, other than Joel, have been quite cooperative,” a court filing said.

Vick’s attorneys also wrote in the filing that “the bankruptcy case may provide a mechanism for the Debtor to recover assets from certain third-parties who may have taken advantage of the Debtor during the pre-petition period.”

Vick’s filing lists Hunton & Williams partners Hill B. Wellford Jr. in Richmond and Arthur E. Schmalz in McLean, Va. as counsel to Joel Enterprises. Wellford and Schmalz couldn’t be reached for comment.

Two law firms are advising Vick on his bankruptcy reorganization: Crowell & Moring in New York and Kaufman & Canoles in Norfolk, Va.

Some of Vick’s debts arise from his defaulting on loans as a result of his imprisonment. Vick was ordered in May to pay $1.1 million to Wachovia after he defaulted on a loan he used to open Atlantic Wine & Spirits and the Tasting Room restaurant in College Park. Smith, Gambrell & Russell partner Thomas Barton and associate Aaron Tady in Atlanta are counsel to Wachovia Corp. Vick also agreed to repay a $2.5 million loan to Royal Bank of Canada. Poyner & Spruill partner Lisa Sumner in Raleigh, N.C., is counsel to the Canadian bank.
