Boyd suffered a non-contact injury during the team's friendly against Queens Park Rangers. He played 45 minutes in the friendly and later went to see knee specialist Dr. Ulrich Boenisch. It was Boyd's fourth match with the club during a strong preseason that had seen him score against Sonnenhof Großaspach and Paris-Saint Germain.
The team says the 23-year-old forward will be out for at least 10 weeks, with the player relaying the same information to fans on his Twitter account.

Boyd had been named to Klinsmann's provisional World Cup roster but didn't make the final 23-man team for Brazil. The injury will keep him from being called for a September friendly against Czech Republic, with another match against European opposition also likely to take place during the same FIFA window.
