Two-time champions Serena and Venus Williams will compete in doubles at the French Open.
The American sisters were handed a wild-card entry on Thursday into the tournament they won together in 1999 and in 2010.
They have not played doubles together at a major since they won Wimbledon two years ago.
The sisters are also expected to compete in singles.
The clay-court Grand Slam tournament starts on Sunday.
The French Open will mark Serena Williams' first major tournament in more than a year. A three-time champion in singles, she hasn't played at a Grand Slam event since winning the Australian Open in January 2017, while pregnant.
