Former Baltimore linebacker Ray Lewis finished his career on top of the football world in February when his Ravens beat the 49ers in Super Bowl XLVII. Now Lewis is headed to the top of the actual world. The retired linebacker plans to climb Mt. Kilimanjaro -- the tallest freestanding mountain in the world -- in June.

Lewis will be scaling the 19,341 feet to the top of Kilimanjaro to raise money and awareness for clean water projects in East Africa.

"In one month, I will climb Mt. Kilimanjaro in Tanzania to raise money and awareness for clean water projects in East Africa," Lewis wrote on his Lockerdome page. "I am so FIRED UP for this adventure, but until then, I need your help to bring clean water wells to thousands of children and families. Show your support by following my TackleKili journey, spreading the word, and donating to TackleKili."
