Novak Djokovic, who has reached the semifinals of Monte Carlo despite contending with a sore ankle, says that playing with this type of injury is something he has never experienced before.

Sky Sports reported that after Djokovic injured his ankle during his Davis Cup win over Sam Querrey, doctors discovered he had a dislocated bone, which they were able to put in back in place.

“Obviously I'm not physically out there feeling my best. Somehow feels that I always miss that half a step,” Djokovic told reporters. “But I'm trying. I'm fighting...I'm experiencing something new this week. To be honest, I think I never been in this particular situation before where wherever I start a match, it's triple the effort that I usually put in energy-wise because there are many things that I'm thinking about. It's the pressure of playing the match, then the ankle, so forth. Obviously I'm physically not up to my maximum capacity. So a lot of things [are] in play."
