Ahead of a record-breaking 24 race calendar, which includes four double-headers and two triple-headers, Croft has taken the decision to stand down from the Emilia-Romagna, Austrian and Azerbaijan Grands Prix.
Croft has also missed this year's pre-season test in Bahrain, having previously been a part of the commentary team in recent years since F1 started to live broadcasted the event.
He will be replaced by BBC Radio 5 Live commentator Harry Benjamin, who led Sky’s coverage on F1 Juniors last year.
Croft has been the lead commentator on Sky since it took over the UK television rights from the BBC in 2012. He has been a permanent fixture at the races and has not missed a grand prix since.
Having originally arrived in F1 as commentator for BBC Radio 5 Live in 2006, when he succeeded Maurice Hamilton, he only missed one race prior to his move to Sky when he skipped the 2007 European Grand Prix due to the birth of his son.
