Olympic sprint champion Lamont Marcell Jacobs has withdrawn from this month's Diamond League meetings in Rome and Oslo after failing to recover from a muscle injury, Italy's athletics federation said.
The 27-year-old, who became the first Italian to win Olympic 100 metres gold in Tokyo last year, picked up the injury during his victory in the 100m in Savona, Italy in May and also missed the Prefontaine Classic in Eugene last weekend.
