Its been nearly a year since Serena Williams last had a match.
I am excited and honoured to be making my comeback as part of the first women to participate in the event, Williams added.
"For this reason, I have sadly announced to the organisers and now to you fans that I won't play this time in Abu Dhabi".
Serena Williams is set to appear on court for the first time since giving birth after confirming she will play at the Mubadala exhibition event in Abu Dhabi, in the United Arab Emirates, next Saturday.
Williams, who got married last month, is now ranked 22nd in the world and would not require a wild card for the Australian Open which begins on January 15. She is expected to compete for her 24th at the Australian Open, the first major of the year.
Williams will face defending French Open champion in an exhibition match.
Churches planning Christmas Eve services
The service will feature a "Service of the Inn", Christmas carols, Scripture readings and Communion led by Pastor Mark Fuerstenau. Robert Baker will speak at the 10:45 a.m. worship service on "Pointing to God", with scripture from Luke 1:46-55.
It is nearly a year since Williams won the Australian Open title, later revealing she was pregnant with her first child, Alexis Olympia who was born in September.
The 23-time Grand Slam champion will play a match on Saturday December 30 at 5:00 PM against the Roland Garros victor Jelena Ostapenko.
Coach Patrick Mouratoglou said in November that no decision had been made over whether Williams would play in the season's first Grand Slam.
