Officials from the National Football League will be before a federal judge Tuesday in Philadelphia asking to throw out 4,200 lawsuits from current and former players.
116 players from the Kansas City Chiefs have joined the suit, asking for around $5 million each in compensation from the league.
The players allege the NFL promotes violence in the game and conceals known cognitive risks from concussions and other blows to the head.
Some of the players suffer from dementia, Alzheimer's, depression and other neurological problems.
The players blame head-to-head contact from the game for their lifelong injuries.
41 Action News asked Chiefs owner Clark Hunt if these lawsuits could change the game. He tells us it could, and while rule changes are often unpopular with fans who allege it takes away from the excitement of the game, he says most fans realize the NFL has the responsibility to look out for its players' health.
A recent study at the University of Michigan found retired NFL players between the ages of 30 and 49 are 19 times more likely to be diagnosed with some form of dementia.
