Weah missed the U.S. U-17 national team camp in Bradenton to stay with PSG. He played on its reserve team Sunday, debuting off the bench in a 3-2 loss to Jura Sud in France's National 2, the fourth level of French soccer.
Weah, who signed his first pro contract with PSG in July, scored three goals in four games last season in the UEFA Youth League.
The UEFA Youth League mirrors the participation of teams in the UEFA Champions League. It also has a component featuring the youth champions of 32 European nations.
