Christian Pulisic will not rejoin the U.S. men’s national soccer team next week, after all.

Another injury, this time a torn calf muscle, will prevent the 20-year-old star from attending training camp and playing in friendlies against Colombia on Thursday in Tampa and Peru on Oct. 16 in East Hartford, Conn.

The U.S. Soccer Federation officially ruled him out Friday, four days after he was named to the squad for what would have been his first national team appearance in almost five months. The injury will also sideline him from Borussia Dortmund, the Bundesliga front-runner.

Tyler Adams — a 19-year-old midfielder from the New York Red Bulls who scored the U.S. winning goal against Mexico last month — was also scratched from the roster. He is suffering from back spasms.

Philadelphia Union winger Fafa Picault (eight goals, four assists) was added to the squad.

Pulisic’s final opportunity to suit up for the U.S. team this year will come Nov. 15 against England at London’s Wembley Stadium and five days later against Italy at a European venue to be announced soon. (Belgium is the likely location.)

Since the Americans' failure last fall to qualify for the World Cup in Russia, Pulisic has appeared in one international match: May 28 against Bolivia in Chester, Pa. — and that was largely for marketing purposes because it took place in his home state.

He skipped the June friendlies at Ireland and France in order to recover from a long season with Dortmund and missed the September games against Brazil and Mexico with an unspecified muscular ailment.

Pulisic has been in terrific form of late, scoring in the UEFA Champions League and Bundesliga and assisting in a league match. Last Saturday, though, he departed a Bundesliga game early and, just before Wednesday’s Champions League match against Monaco, Dortmund announced Pulisic would sit out with the calf injury. He was also ruled out of league action this weekend against Augsburg.

The U.S. squad will begin workouts Monday in the Tampa area. About 25,000 tickets have been sold.
