Former NFL player Derrick Walker has sued the league in federal court, accusing it of not warning him about the risk of football-related concussions.

Walker's lawsuit, filed Monday in Detroit, is one of many across the country by retired players. Walker played tight end in the 1990s for the San Diego Chargers, Kansas City Chiefs and Oakland Raiders. He lives in West Bloomfield, a Detroit suburb.

Walker says he suffers from memory loss, headaches and sleeplessness. Besides the NFL, his lawsuit also names football equipment companies as defendants.

The NFL has vowed to vigorously defend itself against such lawsuits. The 45-year-old Walker played college football at Michigan.
