NBC news reports that 75 former NFL players have sued the National Football League alleging that the NFL concealed the risks of concussions. Riddell - the helmet manufacturer - has also been included in the lawsuit.

According to the lawsuit, the NFL knew or should have known about the link between brain and head injuries and long-term health problems.

Traumatic brain injuries (TBIs) such as concussions can have serious, long term and sometimes-permanent consequences if not detected and treated. TBIs can occur in a variety of circumstances and arise from a blunt or sudden trauma to the head. Often associated with car accidents, TBIs can occur as the result of any blow to the head, such as a motorcycle accident, a bicycle accident or sports injury as is alleged here.

Symptoms of TBIs may not show up immediately and may be vague - such as headaches, dizziness and confusion. However, if you're received a jolt or blow to your head its imperative to seek medical attention immediately. Where you have been involved in an accident, speaking to a brain injury lawyer is important in order to preserve your right to bring a lawsuit and determine your next steps.

Here, the lawsuit alleges that the NFL "knew as early as the 1920s of the harmful effects on a player's brain of concussions; however, until June of 2010 they concealed these facts from coaches, trainers, players and the public."

For more information about TBIs or if you believe you or a loved one has suffered a brain injury as the result of a sport, motorvehicle or any other type of accident, please contact the Sacramento brain injury lawyer and personal injury lawyer at Sette Law Office for a confidential consultation.
