Djokovic has not entered an official grass-court competition between the French Open and Wimbledon since 2010, instead opting for rest and the odd exhibition match. This year, however, the Serbian has accepted a wild card for Eastbourne, an ATP 250 event, where he will be the No 1 seed next week.
Djokovic will join the likes of Gael Monfils, Feliciano Lopez and John Isner on the south coast as the 12-time grand slam champion looks to find rhythm ahead of the start of Wimbledon on 3 July.
He has struggled for form over the last 12 months, failing to win any of the four major tournaments and going past the quarter-finals just once, at the US Open in September.
The 30-year-old began working with Andre Agassi at the French Open last month and the American has suggested the partnership will continue at Wimbledon.
