Billed as a matchup of two of the nation's top quarterbacks, ESPNU's Friday night broadcast of Sheldon vs. Graham-Kapowsin has already suffered a major blow.
Penn State commit and Under Armour All-American Game quarterback Michael Johnson Jr. is expected to miss the nationally-televised contest with an undisclosed shoulder injury.
The 6-foot-3, 185-pound Sheldon star, who is rated the nation's No. 5 dual-threat quarterback by Rivals, confirmed the injury report Friday.
Despite Johnson's absence, Sheldon's contest should still be on note for local football fans, as the Irish will suit up defensive end/tight end Patrick Herbert, a four-star Oregon commit who is the younger brother of star quarterback Justin Herbert.
