Ngata retires from NFL atop Mount Kilimanjaro

Haloti Ngata, one of the most dominant defensive linemen of his era, scaled new heights to announce his retirement.

In an Instagram post, Ngata stood on top of Mount Kilimanjaro -- the world's tallest free-standing mountain -- with a banner that read, "I'm retiring from the NFL on top."

Just a man standing on top of the world with a heart full of gratitude. Thank you Lord for letting me play the game I love for 13 unforgettable years. I'm retiring on top. I might be finished playing football, but I'm holding tight to the friendships, memories and wisdom I've gained along the way.
