Novak Djokovic through to Miami Masters final as Kei Nishikori retires

Novak Djokovic has made it through to the Miami Masters final without hitting a ball due to the retirement of his opponent Kei Nishikori.

The pair were due to go head to head at around 7pm UK time for a place in the final, but the 20th seed has been forced to withdraw with a groin injury.

Nishikori was originally hoping to reach his first final at the tournament after knocking out Roger Federer in three sets in the quarter-finals.

Djokovic, who defeated Andy Murray to reach the final four, will take on either Tomas Berdych or Rafael Nadal in the final.
