Del Potro undergoes second operation on injured knee

Former US Open champion Juan Martin Del Potro, out of action since June 2019, underwent surgery on his right knee in Miami on Monday.

The Argentine posted a photo on social media showing him on crutches with his right leg in a brace and the caption in Spanish and English that said "time to go home to rest" and said thank you "for all the love and support you give me in these difficult times."
