Dorsey Levens blames NFL for brain injuries

ATLANTA (AP) - Jamal Lewis, Dorsey Levens and two other former NFL players have sued the league over brain injuries that they say left them struggling with medical problems years after their playing days ended.

Lewis and Levens, along with Fulton Kuykendall and Ryan Stewart, filed the lawsuit against the National Football League and NFL Properties LLC this week in U.S. District Court in Atlanta.

The players maintain the NFL knew as early as the 1920s of the potential for concussions to harm its players but only went public last year.

"The NFL has done everything in its power to hide the issue and mislead players concerning the risks associated with concussions," the players argue in the lawsuit.

"While athletes in other professional sports who had suffered concussions were being effectively `shut down' for long periods of time or full seasons, NFL protocol was to return players who had suffered concussions to the very game in which the injury occurred," the lawsuit states.

The NFL responded that it has long made player safety a priority and continues to do so.

"Any allegation that the NFL intentionally sought to mislead players has no merit," the league said in a statement to The Associated Press on Thursday. "It stands in contrast to the league's actions to better protect players and advance the science and medical understanding of the management and treatment of concussions."

Each of the four ex-players had long careers in the NFL. Their lawsuit is one of about a half-dozen suits filed against the NFL in recent months by past players who say the league did not do enough to protect them from concussions.

Lewis, 32, is a former running back for the Baltimore Ravens and Cleveland Browns whose 10-year career ended in 2009. Levens, who is 41, also was a running back, playing 11 seasons until his career ended in 2003. Kuykendall, a former linebacker who is 58, played in the NFL between 1974 and 1985. And Stewart, 38, was a safety for the Detroit Lions for five seasons ending in 2000.

The men claim a range of medical problems stemming from their playing days, including memory loss, headaches and sleeplessness.

They are seeking a jury trial and unspecified damages.
