Jason Roy is set to cancel his ECB central contract in order to sign a lucrative deal to play Major League Cricket in the United States this summer.
The World Cup-winning opening batter has been offered a two-year deal worth around £300,000 by the Los Angeles Knight Riders, which he wants to pursue despite the risk it could jeopardise his place in England's squad for this year's 50-over title defence in India.
Roy is currently contracted by the ECB on a so-called incremental deal until October, which gives the governing body some control over his schedule.
In a historic move Roy would become the first England player to walk away from a central contract in order to pursue alternative ambitions with a Twenty20 franchise.
As Major League Cricket clashes with the County Championship and T20 Blast it is understood that the ECB are only prepared to grant Roy the No Objection Certificate required to play if they cancel his incremental deal.
While Roy retains ambitions to play for England the security of the two-year offer he has received from LA Knight Riders is a significant factor in his reasoning.
The ECB have told Roy that his decision will not impact on Mott's selection plans or the next round of central contracts, which are awarded in October.
Mail Sport revealed earlier this month that Mumbai Indians are preparing to offer Jofra Archer a 12-month contract that would take precedence over his ECB deal and Roy's move reflects this trend, as the LA Knight Riders are owned his IPL team, Kolkata Knight Riders.
The inaugural Major League Cricket which launches in Texas this summer represents a particular threat to English cricket due to scheduling, with Mail Sport revealing on Wednesday that the new competition will expand into August next year, leading to a clash with the Hundred.
Four of the six franchises in Los Angeles, New York, San Francisco, Seattle, Texas and Washington are owned by IPL teams who are offering salaries of up to £300,000, compared to a top rate of £125,000 in the Hundred.
