The annual East vs. West match-up will be televised live on NBC at 1:00 p.m. EST and will feature the nation's top 90 high school football players.
"Kelly, Jr, is a talented athlete whose leadership and teamwork qualities have made him a standout at Webb School of Knoxville High School," said Mark Davis, deputy assistant Secretary of the Army for Marketing.
"Only the strongest wear the Army colors and we are proud to welcome all of the U.S. Army All-American Bowl players and commend each of them on their selection."
Kelly is verbally committed to stay at home and play for Tennessee in college.
The 5-foot-11, 195-pounder is rated as a Scout.com four-star prospect, the No. 12 safety in the country.
"Kelly, Jr. is a very headsy and smart player in the secondary," Scout.com National Analyst Chad Simmons informed.
"He plays running back and safety in high school, but he will be defense all the way in college. He has very good range in the secondary and he can cover a lot of ground. He is better when moving forward than he is when backing up in coverage. Against the run he is very good because of his size and ability to tackle. He has above average ball skills."
For more than 13 years, the U.S. Army All-American Bowl has been the nation's premier high school football game, serving as the preeminent launching pad for America's future college and NFL stars.
In the 2013 NFL Draft, there were a total of 8 U.S. Army All-American Bowl Alumni drafted in the first round. The 2013 U.S. Army All-American Bowl drew a crowd of 40,133 to the Alamodome, and was the most-watched sporting event on television over the weekend, excluding the NFL playoffs.
