Tennis legend Roger Federer announces retirement

Swiss tennis legend Roger Federer on Thursday announced that he plans on retiring from competitive tennis after competing in the Laver Cup tournament next week in London.

Federer, who was ranked No. 1 tennis in the world for 310 weeks, called it a "bittersweet decision," but said he has struggled over the past three years with injuries and surgeries.

"I’ve worked hard to return to full competitive form. But I also know my body’s capacities and limits, and its message to me lately has been clear," Federer wrote on what appears to be his personal website. "I am 41 years old. I have played more than 1500 matches over 24 years. I must recognize when it is time to end my competitive career."

He said he will "never leave" the sport and plans on playing "in the future, of course, but just not in Grand Slams or on the tour."
