In 1999, Spielman came close to making a comeback, but he was forced to retire before any more serious injuries could be sustained after suffering another neck injury before the regular season even began.
Scott Stevens
Scott Stevens is another example of a player who had a great career but was forced to retire due to a series of injuries over the years. He announced his retirement after the 2003–2004 season, citing multiple concussions during his two decades on the field.

He didn’t actually finish the season because he was diagnosed with post-concussion syndrome in November of that year, forcing him to sit out. Even today, concussions are one of the most dangerous hazards for football players.
