Years of training and competing on the gridiron takes its toll, and Armstead said his ailment was a knee injury he constantly had to battle through since his third year in the league."I didnt see a practice field at all, and not because I didnt want to or the Dolphins just wanted me to rest. Its like I literally couldnt walk," he said during an appearance on the"Nightcap Show.""After a game on Sunday, I wouldnt be able to walk on my own, under my own power, until Wednesday, Thursday. So, I was only able to play under the pain meds. I couldnt put any pressure on my knee, so it was like, I cant keep doing that to myself."So, no, Armstead is not going to be one of those retirees who will get the urge to get back on the field come Week 1."I think Im done, Im at peace with it. Im excited to be on this side to talk about the game, share my knowledge and experience."After being in the game for so long, and playing football for so long since five years old, its definitely bittersweet. Its my first year without it after 28 years, so Ill see what this life is going to be like without football. Im so grateful and appreciative for it, but Im excited for my future."While he may be off the sidelines, Armstead still wants to make an impact on the game he loves dearly, especially for those players who continue to put their bodies on the line each year to hunt for a Super Bowl title alongside their teammates.Follow Fox News Digitalssports coverage on X, and subscribe tothe Fox News Sports Huddle newsletter.
