Miami: World number two Novak Djokovic received a walkover into the final of Sony Open on Friday after Japan`s Kei Nishikori withdrew with a groin injury.

Nishikori had reached the last four after registering a pair of three-set upsets, defeating Spanish fourth seed David Ferrer in fourth round followed by a quarter-final win over Swiss 17-times grand slam winner Roger Federer.

The ATP Tour made the announcement just before the 20th seeded Nishikori was about to take to centre court.

"Very sorry to say that I have to pull out today," said Nishikori on his Facebook page. "Very disappointed and I am obviously very sorry for any fans that wanted to come out for this match.

"This tournament is very special to me and look forward to coming back in the years to come.

"I will work with my medical team to be back healthy as soon as possible."

The walkover was the second of the tournament for Djokovic, the Serb also receiving a free pass in the third round when Florian Mayer pulled out, also with a groin injury.

Djokovic, a three-time winner on the Miami hardcourts, will now await the winner of the other semi-final between world number one Rafa Nadal and Czech Tomas Berdych.

Djokovic should be well-rested for Sunday`s final, not having played in four days and contested just three matches the entire tournament.

"It`s not the first time it happens to me (a walkover), maybe it is the first time twice in the same tournament but it is the way it is and you kind of have to deal with that mentally," said Djokovic. "I practiced today, 30-40 minutes on centre court, got good rhythm and trying to keep up with what I have been doing.

"I won in Indian Wells, gave me a lot of confidence, played a lot of matches so hopefully it will pay off."
