Jankovic won her first grass-court title at Edgbaston in 2007
Defending champion Jelena Jankovic has withdrawn from next week's DFS Classic tournament at Edgbaston.
The Serbian struggled through the French Open with an injury and lost to Ana Ivanovic in Thursday's semi-final.
"We do know that she was all set to come here," Edgbaston tournament director Marjory Howie told BBC WM.
"But she had a forearm injury in Paris, and she just won't be able to make it. If they're injured, sadly, we can't do anything about it."
Jankovic's opponent in last year's Edgbaston final, Maria Sharapova, is also missing the tournament.
However, surprise French Open finalist Dinara Safina is expected to play in Birmingham next week.
