Wife of former Packers running back is suing NFL

GREEN BAY (WITI) -- The wife of a former Green Bay Packers running back is suing the NFL.

Lew Carpenter played from 1959 to 1963 for Vince Lombardi.

He died in 2010.

The lawsuit says studies of Carpenter's brain after his death showed long-term trauma.

The lawsuit blames the NFL for putting him in danger and for covering up studies showing a link between concussions and brain damage.
