Nearly 20 attorneys and firms involved in the NFL concussion litigation are challenging a lead attorney’s proposal for divying up $112 million in attorney fees, which had allocated the lion’s share to his firm.

According to court filings, 16 firms and one former member of the plaintiff’s steering committee have filed objections to the proposal that Christopher Seeger submitted to the court in mid-October. That proposal had included more than $70 million for his firm, Seeger Weiss.
