Former BYU and Philadelphia Eagles tight end Chad Lewis, joined by former New England Patriots linebacker Tedy Bruschi and former Tennessee Titans coach Jeff Fisher, climbed to the summit of Mount Kilimanjaro this week as part of their eight-day journey to bring attention to the Wounded Warrior Project. Lewis, Bruschi and Fisher ascended to the top of the 19,340-foot summit, known as "the roof of Africa," along with four soldiers who suffered injuries in the line of duty.
