He's just started to get back into cricket after playing a few games with Durham.It's quite chaotic.It'll be a great opportunity for some, and England already had a large squad for cover, including coronavirus.England is happy that this series isn't the most prominent. The Twenty20 Series is very important, and it's not too late for them to organize for the World Cup.Although the 50-overs stuff is not important, it will cause disappointment in the England camp if they miss the Twenty20 series.
