Are the Black Caps running low on fit players?

Black Caps coach Rob Walter will be thankful New Zealand Cricket has done its best to grow depth at international level as his side continues to be ravaged by injuries."We've kind of learned to work on the fly," Walter told media on the eve of the ODI series against India.Devon Conway's concussion after colliding with team-mate Matt Henry at training on Tuesday is the latest in a growing list of injuries affecting the team as they move into the second phase of the Indian series.On Monday, Mark Chapman (hamstring) and Rachin Ravindra (shoulder) were ruled out of the five-match ODI series as they continue to rehabilitate their respective injuries.Matt FisherKerry Marshall/www.photosport.nz"The planning for this started a long time ago, we knew what we were going to be faced with and that we'd have to manage it. Obviously you start off with a plan in mind and this was months ago, talking to the players almost in June and July that we'd have to manage this," Walter said."You're faced with different scenarios and injuries and so you have to adapt on the fly to those."Walter and the selectors are always managing their pace bowling attack.Lockie Ferguson and Matt Henry both missed parts of the T20 series with injuries.It was decided last month that Will O'Rourke would miss the Indian tour (hamstring and calf) in the hope that he'll be at peak fitness for the four-Test series in Australia in December and January.Elsewhere Ben Sears (ankle) and Zak Foulkes (hip) are still rehabbing from injuries.Jacob DuffyKerry Marshall/www.photosport.nzSo Walter will spread Henry, Ferguson, Jacob Duffy, Nathan Smith, Blair Tickner, Kristian Clarke, Matt Fisher and Kyle Jamieson over the ODI series."Ultimately, we're just trying to do the best we can for our players and then understanding when you're playing 10 games of short format cricket in 20 days and then going into six test matches it's just not possible to keep the same 11 guys turning up, especially from a fast bowling point of view," Walter said.
