Manchester United manager Michael Carrick has named 15-year-old forward JJ Gabriel in the 25-man senior squad for Friday's pre-season friendly against Rosenborg in Trondheim, Norway.
The academy player could make his first-team debut in the match.
Gabriel, who turns 16 in October, is the only addition to the traveling party that lost 1-0 to Wrexham in Finland.
He replaces striker Ethan Wheatley after being held out of the Finland fixture due to returning to training less than a week prior.
The London-born winger scored 29 goals in 32 appearances across all competitions for the Under-18 squad last season.
He helped the team reach both the FA Youth Cup and Premier League Under-18 cup finals, narrowly missing the league's top scorer title.
Squad and Absentees
The traveling roster includes Tom Heaton, Radek Vitek, Harry Maguire, Leny Yoro, Luke Shaw, Ayden Heaven, Mason Mount, Joshua Zirkzee, Patrick Chinazaekpere Dorgu, Andrey Santos, Bryan Mbeumo, Chido Obi, Jack Fletcher, Tyler Fletcher, Harry Amass, Toby Collyer, Dan Gore, Dermot Mee, Shea Lacey, Ethan Williams, Jaydan Kamason, Jacob Devaney, Jim Thwaites, Dan Armer, and JJ Gabriel.
Several senior players are unavailable for the fixture. Forward Benjamin Sesko, goalkeeper Karl Darlow, and defender Matthijs de Ligt are sidelined with injuries.
Newly signed 18-year-old winger Tynan Thompson was left out after his £8 million transfer from Tottenham Hotspur.
Gabriel's first-team inclusion follows interest from club officials, including Director of Football Jason Wilcox, who convinced him to stay at United last summer.
Former manager Ruben Amorim initially promoted the teenager to senior training sessions, where he has remained a regular participant.
Uncertainty remains over striker Chido Obi, who did not play against Wrexham despite full second-half squad rotations.
United officials are evaluating whether to retain him or approve a loan deal in the coming weeks.
Winger Ethan Ennis missed the pre-season squad after a minor training injury requiring several weeks of recovery.
He had a 45-appearance loan spell with Fleetwood Town in League Two last season, after which United extended his contract by 12 months.
Goalkeeper Solomon Honor was loaned to Southport for the season.
Under the agreement, he will maintain regular training at Carrington as a training goalkeeper while competing in non-league fixtures.
