Former women's Ballon d'Or winner Ada Hegerberg has undergone surgery on a stress fracture to her left tibia, the Norwegian's club Lyon announced on Tuesday. The European champions said Hegerberg had the operation last Friday, but has recovered from a knee ligament injury which required surgery in February. "Hampered since April 2019 by persistent pain in the left tibia, the medical team diagnosed a stress fracture and first undertook a treatment to accelerate the recovery," Lyon said in a statement. The 25-year-old forward won her fifth Champions League title last weekend despite missing out on the 'Final Eight' tournament in Spain, where Lyon beat Wolfsburg 3-1 in the final. "Every time I step on the pitch I'm giving 100 percent, and sometimes the body says stop," Hegerberg, who joined Lyon in 2014, said in a Twitter post. "While my knee has fully recovered and is ready to go, I took advantage of this particular period to take care of a year-old injury. This is just a slight delay. See you guys very soon." Hegerberg won the inaugural women's Ballon d'Or award in 2018. fjt/jc/mw
