Maria Sharapova will feature alongside eight of the world's top 10 if she accepts a wildcard for next month's Aegon Classic in Birmingham.
Britain's Johanna Konta will play, along with Garbine Muguruza, Karolina Pliskova and Angelique Kerber, who will return to world number one on Monday.
BBC Sport understands Sharapova will be offered a wildcard for Birmingham.
The Russian, who returned from a 15-month doping ban last month, lost to Eugenie Bouchard in Madrid on Monday.
Her involvement in Spain, courtesy of another wildcard, ended in the second round courtesy of a 7-5 2-6 6-4 defeat to the Canadian, who had been critical of the Russian, calling her a "cheat" and saying she should never have been allowed to play again.
