The US Open has received strong criticism following its decision to hold its mixed doubles competition as a standalone event before the start of the Slam from 2025.
Organisers said it hoped the move would encourage top singles players to participate in the mixed doubles, which will be held over two days in the week leading up to the start of the main draw in New York.
However, the decision has been described as a "profound injustice" by last year's winners Sara Errani and Andrea Vavassori amid a backlash from players.
The US Open mixed doubles will be held on 19-20 August, before the hard-court Slam - which from this year is expanding to a 15-day event - begins on Sunday, 24 August.
