Buchanan Ingersoll & Rooney has closed the book on a lawsuit alleging the firm didn’t do enough to scrutinize a $19 million investment that a Tampa-area surgeon agreed to put into a local Arena Football League team.

Buchanan Ingersoll and the surgeon, Dr. Robert Nucci, filed a stipulation Friday in Tampa federal court, indicating that they had reached a settlement of Nucci’s lawsuit against the firm and agreed to dismiss the case. U.S. District Judge Elizabeth A. Kovachevich formally signed off on the dismissal Saturday. The terms of the settlement were confidential.
