Tomljanovic runs out of time in returning from knee surgery ahead of Roland Garros

Australian tennis star Ajla Tomljanovic will not be competing at this year's Roland Garros, as she is yet to recover from a knee surgery.

The 30-year old was hoping to make a return to the WTA tour after undergoing surgery on her knee, and had set the French Open as a potential return point. However, her medical hiatus will likely be extended, as she has not been medically cleared to compete in Paris.

Tomljanovic has not played a match since last November and was forced to miss her home Grand Slam at the Australian Open. Following her withdrawal from Roland Garros, the Australian will be replaced by a lucky loser who is beaten in this week's qualifiers.
