The family of a deceased professional football player wants their suit against the National Football League and helmet-maker Riddell severed from the consolidated litigation pending in federal court so the case can be tried in state court.

The family of Adrian Robinson, who was a defensive lineman for the Pittsburgh Steelers and Denver Broncos before he committed suicide at age 25, filed a motion Wednesday seeking to remand their suit from the multidistrict litigation pending in the U.S. District Court for the Eastern District of Pennsylvania back to state court where it was initially filed.

The family had filed the suit, Robinson v. National Football League, in May in the Philadelphia Court of Common Pleas, and, soon after, the defendants removed the case to the MDL.
