Co-lead class counsel in the NFL concussion litigation settlement has pushed back against third-party funding company Thrivest’s efforts to delay disputed payments to claimants pending an appeal over the validity of lending agreements the company entered into with ex-players.

Seeger Weiss attorney Chris Seeger, who is co-lead counsel in the litigation, on Tuesday asked the U.S. Court of Appeals for the Third Circuit to deny the motion for stay that Thrivest filed with the court last week.
