Raising concerns over pacer Trent Boult's deal with New Zealand Cricket (NZC), former Black Caps coach Mike Hesson said his contract is "untidy" and "will open a can of worms". Boult gave up his New Zealand contract last August to spend more time with family and continue playing franchise cricket around the world. Boult, who features in the IPL, will play in the inaugural season of United States Major League Cricket, starting next month. The 33-year-old left-arm pacer wasn't a part of NZC's latest central contract list announced last week but the board offered him a casual playing agreement.
