Wallace, a four-star outside linebacker/rush end prospect out of John Curtis Christian High School in River Ridge, La., joins the Sun Devils as a member of the 2015 class.
If certified by the NCAA Clearinghouse, the 6-foot-4, 215 pound Wallace would be able to play for ASU this season. He is likely to play Devil Backer for the Sun Devils and could have a chance to impact the depth chart as a true freshman at a position that lacks depth and experience.
ASU worked sophomore Alani Latu and redshirt freshman Ismael Murphy-Richardson at Devil backer during Spring football, neither of whom has played the position in a game. Highly anticipated junior college addition Davon Durant was expected to play at the position as well but his status is now uncertain following suspension from the program due to an arrest for alleged domestic battery.
The No. 261 overall prospect and No. 21 outside linebacker in the 2015 class, Wallace had nine sacks and 16 tackles for loss as a high school senior.
Wallace was bumped to a four-star prospect by Scout.com after an impressive performance in January's Semper Fidelis All-American Bowl.
Wallace is ASU's seventh scholarship player from Louisiana on its projected 2015 roster.
