Former US Open champion Juan Martin del Potro will make a comeback at next month's Argentina Open following four bouts of knee surgery.
The 33-year-old has not competed since appearing at Queen's back in 2019, when he fractured his kneecap in his first round match against Denis Shapovalov, but has now accepted wildcards into both the tournament in Buenos Aires and the Rio Open in Brazil the following week.
Both are clay-court tournaments with the ATP 250 Argentina Open starting on Monday, February 7, while the ATP 500 event in Brazil gets underway a week later on February 14.
