The legal equivalent of folding chairs and ladders are flying in World Wrestling Entertainment’s concussion litigation involving some 50 former wrestlers.

WWE asked a Connecticut federal judge to impose Rule 11 sanctions Monday against attorneys for the wrestlers who say head injuries sustained while working for WWE are either causing or putting them at risk for neurological disease. WWE and its K&L Gates counsel accuse plaintiffs of cribbing almost blindly from a 2012 complaint filed by former football players in their own head-trauma lawsuit against the National Football League.
