New Zealand captain Kane Williamson is set to return to Test cricket for the first time since November after being included in their initial 20-man squad for next month's tour of England. New Zealand Cricket (NZC) on Tuesday named an extended squad for the three-Test series to include cover for players likely to miss two warm-up games at the end of this month due to their involvement in the ongoing Indian Premier League (IPL). The squad will be trimmed down to 15 before the first Test at Lord's on June 2. Williamson's elbow injury kept him out of a Test match in India in December and home series against South Africa and Bangladesh. The 31-year-old is currently playing for Sunrisers Hyderabad in the IPL and could be among those absent for the warm-up matches, along with Tim Southee, Trent Boult, Devon Conway and Daryl Mitchell.
