The Williams sisters are back playing doubles tennis ahead of the U.S. Open. Serena and Venus Williams are set to take part in the Cincinnati Open that begins next week after receiving a wild-card entry.

The sisters are also expected to potentially play at the U.S. Open later this month, Jon Wertheim of Tennis Channel reported last month.

Serena, 44, will partner Venus, 46 in doubles at the Cincinnati Open, but will not play singles.
