Liverpool's principal owner John Henry and chairman Tom Werner will miss the FA Cup semi-final against Everton having flown back to the United States.
The pair were on Merseyside earlier in the week to oversee the departures of director of football Damien Comolli and head of sports medicine and sports science Peter Brukner.
However, the club have confirmed they opted to to fly home to watch Boston Red Sox's first home match of the Major League Baseball season on Friday night.
Henry and Werner were widely expected to attend the Wembley showdown against the club's near-neighbours - which has taken on additional significance in the wake of poor recent league form - but it turned out their presence was for more pressing business matters.
The two leading figures in Fenway Sports Group, Liverpool's owners, held talks with manager Kenny Dalglish during their time in the city but Werner said on Thursday that the Scot's position was not under immediate threat.
