Fifth seed Kei Nishikori has played down fears over his leg injury after his five-set win over Simone Bolelli in the first round of Wimbledon.
The Japanese star struggled to shake off the unseeded Italian, and needed an injury time-out for a suspected calf injury midway through the final set.
However, he told BBC Sport: "I'm very happy to win the match today. He's a tough player on grass - we played five sets last year. My leg should be OK. It was a little bit sore last week, but it's getting better. It wasn't easy to play three hours."
Nishikori will meet Santiago Giraldo in the next round.
