Tommie Harris scaled some impressive heights during seven seasons with the Bears from 2004-10, most notably becoming the team's first defensive tackle to be voted to three straight Pro Bowls.
But that doesn't compare to what Harris is doing this week; he will join former NFL star Ray Lewis and a team of climbers on a 19,340-foot trek up Mt. Kilimanjaro in Tanzania, Africa, in an effort to help raise more than $500,000 for WorldServe International's clean water projects.
Pros for Africa is a volunteer-led, nonprofit organization based in Oklahoma City that encourages professionals in all fields to share what they know, have and create with the children of Africa.
"I can think of nothing better than a climb like this to raise awareness of the need for clean water," said Pros for Africa co-founder Bill Horn. "One billion people need this basic human right at this moment."
Those interested can track the progress of the climb virtually at TackleKili.org and through social media at Lockerdome.com, where they can provide input about team gear, wardrobe, meal selections on the mountain, or make tax-deductible contributions to TackleKili.
Harris was selected by the Bears with the 14th pick in the 2004 draft. He appeared in 104 games with 90 starts, recording 286 tackles, 28.5 sacks, six forced fumbles, seven fumble recoveries, one interception and 38 tackles-for-loss. After leaving the Bears, the Oklahoma product played one season with the Chargers in 2011.
