Indianapolis Colts at New England Patriots

FILE - This Jan. 10, 2010, file photo shows New England Patriots linebacker Junior Seau before an NFL wild-card playoff football game in Foxborough, Mass. The family of Junior Seau has sued the NFL, claiming the former linebacker's suicide was the result of brain disease caused by violent hits he sustained while playing football. The wrongful death lawsuit, filed Wednesday, Jan. 23, 2013 in California Superior Court in San Diego, blames the NFL for its "acts or omissions" that hid the dangers of repetitive blows to the head.
