IOWA CITY, Iowa (AP) — The University of Iowa is paying an outside lawyer $280 per hour to investigate unspecified NCAA violations in its women’s volleyball program. A letter released Tuesday shows the university hired the law firm Bond, Schoeneck & King on May 4 for “review, evaluation and counsel regarding potential NCAA rules violations.”

Attorney Jason Montgomery in the firm’s Overland Park, Kansas, office is the primary lawyer and billing $280 per hour. Other attorneys and paralegals charging between $140 and $445 per hour may also be assigned work.

Athletic director Gary Barta reported what he called serious rules violations to the NCAA on Monday. He also put coach Bond Shymansky on leave in accordance with his contract, which requires a 30-day written notice before the university could fire him for cause. Shymansky’s contract runs through the 2022 season and pays him a base salary of $215,000. If Shymansky is fired without cause, the university would have to pay him $600,000. But if he resigns before July 1, he would be required to pay $300,000 in damages to Iowa.
