MANCHESTER UNITED new boy Leny Yoro was seen using crutches and wearing a protective boot at the club’s Los Angeles training base this week.
The 18-year-old was forced off during United’s pre-season friendly against Arsenal on Saturday.
He appeared to suffer a non-contact ankle injury during the first half and limped off with assistance from a physio.
Erik ten Hag admitted he and his team were “especially careful” with Yoro in the build-up to the match as he had only completed a few training sessions.
While he remained hopeful the injury would not be serious at the time, the French defender has since been seen using crutches.
He was also spotted wearing a protective boot at United’s UCLA training base in California.
The Red Devils are understood to be assessing the extent of the issue.
Yoro joined Man Utd in a £52million transfer from Lille earlier this month.
Upon his arrival at Old Trafford, he said: “Signing for a club with the stature and ambition of Manchester United so early in my career is an incredible honour.
“Since my first conversations with the club, they set out a clear plan for how I can develop in Manchester as part of this exciting project, and showed a lot of care for me and my family.

“I know about the history of young players at Manchester United and feel it can be the perfect place to reach my potential and achieve my ambitions, together with my new team-mates. I cannot wait to get started.”
Rasmus Hojlund also appeared to suffer an injury during the 2-1 defeat to Arsenal.
The striker limped off with what looked to be a hamstring issue.
