Trent BoultNew Zealand fast bowler Trent Boult is in line to make a comeback to the Black Caps playing XI in the second Test against England in Edgbaston. Boult joined the squad in the UK last week, having opted to return home after IPL 2021 was postponed instead of heading straight to England.Kiwi head coach Gary Stead had indicated that Boult might miss both Tests against England. However, a new quarantine rule in the UK has allowed the left-arm pacer to start training immediately after landing in the country.As a result, he will be available for selection and New Zealand might be tempted to tinker with their pace attack for the second Test.Gary Stead update, Birmingham:- Pace bowlers from Lord’s won’t all play 2nd Test- Trent Boult available & likely to return- Mitch Santner ruled out with his cut left index finger - Kane Williamson’s left elbow injury being monitored & a decision to be made tomorrow#ENGvNZ pic.twitter.com/2o46zoXWqw— BLACKCAPS (@BLACKCAPS) June 8, 2021Trent Boult's return will bolster the Black Caps' pace attack for the second Test.
