Veteran batsman Ross Taylor has sent a scare through the Blackcaps camp, limping out of training in Christchurch with an apparent calf injury.
As the NZ men assembled in Christchurch, the 37-year-old faced only six balls in the nets, before appearing to tweak his left calf.
Coach Gary Stead says Taylor will be assessed by medical staff later on Monday.
Taylor missed the first two of three one-day internationals against Bangladesh with a hamstring injury, but returned for the series finale in Wellington, where he scored only seven runs.
Fifteen of the 20 Blackcaps selected for England are training at Lincoln in the first of two three-day camps, before departing on May 16.
Kane Williamson, Trent Boult, Mitchell Santner and Kyle Jamieson are unavailable on Indian Premier League duty, while batsman Will Young is playing for English county side Durham.
The Blackcaps will play two tests against England at Lord's and Edgbaston, before the World Test Championship final against India at Southampton, beginning on June 18.
