Four Florida law firms that banded together into a limited liability company are disputing attorney fees in nearly 200 cases that resolved under the National Football League’s settlement over concussion-related conditions.

The firms, which formed a professional limited liability company called Neurocognitive Football Lawyers PLLC, filed objections to attorney liens filed in 184 cases pending in the U.S. District Court for the Eastern District of Pennsylvania. The objections, filed Tuesday, contend that the attorneys who filed the liens at issue do not currently represent the 184 former players, and those attorneys failed to properly file those liens with the court, or provide any material benefits to their former clients.
