Striker Rasmus Hojlund and £52m new-boy Leny Yoro both suffered first-half injuries as Manchester United lost their opening US tour game against Premier League rivals Arsenal in Los Angeles.
Hojlund had given his side a 10th-minute lead when he burst onto Marcus Rashford’s first-time pass, outmuscled young defender Ayden Heaven, then beat Karl Hein with a shot through his legs.
The Dane then turned a low Aaron Wan-Bissaka cross wide from close range before seeming to experience a muscle injury after 15 minutes that meant he could not continue.
Yoro’s exit was equally innocuous.
